Languages :: PHP :: Sending a Link
By: tadpole03 U.S.A.  Date: 19/09/2003 00:00:00  English  Points: 125 Status: Answered

Hi,

I'm in the process of writing a 'send to a friend' script but could do with your advice on the actual sending of the link.

I'm using the following code at the mo:

<?

$recipient = "$friendsemail ";
$subject = "myTitle";
$mailheaders = "From: myEmail <$youremail>\n";
$mailheaders .= "Reply-To: <$youremail>";

$msg = "$yourname wrote:\n";
$msg .= "$yourmessage\n";
$msg .= "\n";
$msg .= "<A HREF="http://www.myUrl.com\n">http://www.myUrl.com\n</a>";

mail($recipient, $subject, $msg, $mailheaders) or die ("Couldn't send mail!");

?>

The users will be on a page, then click 'Send to a Friend' which will take them to the form page - I obviously want to include a link to the page they've just come from prior to the form. This has to be dynamic as there are many, many different pages.

Any help you can give will be greatly appreciated!!!!

Change $msg .= "<A HREF="http://www.myUrl.com\n">http://www.myUrl.com\n</a>"; to
$msg .= "<A HREF="http://http://$_SERVER[">http://http://$_SERVER[</a>'HTTP_HOST']$_SERVER['PHP_SELF']";

$msg .= "<A HREF="http://$_SERVER[">http://$_SERVER[</a>'HTTP_HOST']$_SERVER['PHP_SELF']"

Hi,

Many thanks for your input.

Unfortunately I'm getting an error:
Parse error: parse error, expecting `T_STRING' or `T_VARIABLE' or `T_NUM_STRING'

Any ideas?

Try taking out the apostrophes.
$msg .= "<A HREF="http://$_SERVER[HTTP_HOST]$_SERVER[PHP_SELF]">http://$_SERVER[HTTP_HOST]$_SERVER[PHP_SELF]</a>"

I forgot to add the semicolon at the end, that may be your problem.

Hi,

We're nearly there!

Right - there's a link contained in the mail now but it is a link to the actual php script. I need the link to be to the page that the user clicked prior to the form.

1.They see a page they want to send,
2.They click 'Send to a Friend'
3.This opens a page containing the form.

Matt
By: akdov Date: 19/09/2003 03:58:00 English  Type : Comment
Ok, try this then.
$msg .= "<A HREF="http://$_SERVER[HTTP_REFERER]">http://$_SERVER[HTTP_REFERER]</a>";
By: tadpole03 Date: 19/09/2003 04:15:00 English  Type : Comment
Ooohhh... how exciting!

Nearly done - that sends the link to the form page where as we want the one before that, if you get my meaning? So, the users on the desired page, they click send to a friend which opens a new page with the form on - this is where we're sending them back to at the mo.

Would it make a difference if I popped the form in a window then used this script?

Many thanks again,

Matt

remove single qoutes inside a "..." syntax:
$msg .= "<A HREF="http://$_SERVER[HTTP_HOST]$_SERVER[PHP_SELF]">http://$_SERVER[HTTP_HOST]$_SERVER[PHP_SELF]</a>" ;
By: moseack Date: 19/09/2003 04:26:00 English  Type : Comment
add to the form page (which has to be php allso)
<input type="hidden" name="ref_url" value="<?php echo $_SERVER[HTTP_REFERER]; ?>">

and to you form procsesing script:
$msg .= $ref_url;
By: akdov Date: 19/09/2003 04:27:00 English  Type : Comment
Ah, ok, now I see what you're doing.
In the form, you need something like this.
<input type="hidden" name="refer" value="<? echo '<A HREF="http://">http://</a>'.$_SERVER[HTTP_REFERER]; ?>" />

That will pull the link from the page you clicked to get there.

The in your PHP.
$msg .= $refer;

By: VGR Date: 19/09/2003 17:09:00 English  Type : Comment
in case the http_referer isn't set, you could use $script_name.$query_string

if ever you still have this problem, I can show you how I did it for a site I have

Hi,

Sorry if I'm being totally dense - now there's no link being returned in the mail!

I've saved the form as php itself and added:
<input type="hidden" name="ref_url" value="<?php echo $_SERVER[HTTP_REFERER]; ?>">

inside the form.

And my php now reads:
<?

// Configuration of recipient and subject.

$recipient = "$friendsemail ";
$subject = "mySubject";
$mailheaders = "From: myMail <$youremail>\n";
$mailheaders .= "Reply-To: <$youremail>";

$msg = "$yourname wrote:\n";
$msg .= "$yourmessage\n";
$msg .= "\n";
$msg .= $ref_url;

mail($recipient, $subject, $msg, $mailheaders) or die ("Couldn't send mail!");

?>

I'm a little confused!

Can you post a link to a page that uses the refer link?
By: VGR Date: 19/09/2003 17:27:00 English  Type : Comment
please read this : <A HREF="http://us4.php.net/manual/en/language.types.array.php">http://us4.php.net/manual/en/language.types.array.php</a>

"Array do's and don'ts
Why is $foo[bar] wrong?

You should always use quotes around a string literal array index."

and write this as <input type="hidden" name="ref_url" value="<?php echo $_SERVER['HTTP_REFERER']; ?>">

Anyway, like I said, I doubt this will always work, while using $SCRIPT_NAME or PHP_SELF and QUERY_STRING (or PATH_INFO) always will...

for instance the link I send via email is :

$lienext="{$HTTP_HOST}{$REQUEST_URI}"; // (yes, I've register_globals=On)
By: tadpole03 Date: 19/09/2003 17:41:00 English  Type : Comment
I'm completely lost now, I've tried $msg="{$HTTP_HOST}{$REQUEST_URI}"; in the php but it just returns the recommend.php url. I need the url before the form.

Sorry I'm slow at this - I'm a Flash man by trade :)
By: VGR Date: 19/09/2003 17:47:00 English  Type : Comment
at the moment when you build the button "send to a friend" 's link, you add the above "link" as a parameter (urlencoded) towards to "form page". In there you rerieve it, urldecode it, and are ready to send it by email.

no ?

Hi,

Thanks for sticking with this! Just to recap, this is where I am at the mo:

Step One: HTML page containing this link:
<a href="send_pagetest03.php" $lienext="{$HTTP_HOST}{$REQUEST_URI}">sent to a friend </a>

Step Two: PHP page with the following form:
form name="form1" method="post" action="recommend.php">
<input type="hidden" name="ref_url" value="$lienext">
Your Name:
<input type="text" name="yourname">


Your Email:
<input type="text" name="youremail">


Friends Email:
<input type="text" name="friendsemail">


Your Message:
<textarea name="yourmessage"></textarea>




<input type="submit" name="Submit2" value="Recommend">
</form>

Step Three: PHP Script as follows:
<?


// Configuration of recipient and subject.

$recipient = "$friendsemail ";
$subject = "mySubject";
$mailheaders = "From: myEmail <$youremail>\n";
$mailheaders .= "Reply-To: <$youremail>";

$msg = "$yourname wrote:\n";
$msg .= "$yourmessage\n";
$msg .= "\n";
$msg .= $ref_url;

mail($recipient, $subject, $msg, $mailheaders) or die ("Couldn't send mail!");

?>

As I've already said, I'm new to this and am trying to get me noggin' around it all!

Your HTML is wrong. You can't have a variable like that in HTML.
Try:

<a href="send_pagetest03.php">sent to a friend </a>

Step Two: PHP page with the following form:
form name="form1" method="post" action="recommend.php">
<input type="hidden" name="ref_url" value="{$HTTP_HOST}{$REQUEST_URI}">
Your Name:
<input type="text" name="yourname">


Your Email:
<input type="text" name="youremail">


Friends Email:
<input type="text" name="friendsemail">


Your Message:
<textarea name="yourmessage"></textarea>




<input type="submit" name="Submit2" value="Recommend">
</form>

Step Three: PHP Script as follows:
<?


// Configuration of recipient and subject.

$recipient = "$friendsemail ";
$subject = "mySubject";
$mailheaders = "From: myEmail <$youremail>\n";
$mailheaders .= "Reply-To: <$youremail>";

$msg = "$yourname wrote:\n";
$msg .= "$yourmessage\n";
$msg .= "\n";
$msg .= $ref_url;

mail($recipient, $subject, $msg, $mailheaders) or die ("Couldn't send mail!");

?>

it's perfectly correct with two conditions :
1) you've register_globals=On ; else please change the FORM definition (2nd script) using $_GET[]
2) change this :
<a href="send_pagetest03.php" $lienext="{$HTTP_HOST}{$REQUEST_URI}">sent to a friend </a>

into
<a href="send_pagetest03.php?lienext="<?php echo urlencode($HTTP_HOST.$REQUEST_URI);?>">sent to a friend </a>

Here we go again - can't see what I'm doing wrong boys - it's getting later here in England and I'm going to have to get the lager out in a second as my brain is starting to hurt!

Here's what I've got:

1)HTML with this link:
<a href="send_pagetest03.php?lienext="<?php echo urlencode($HTTP_HOST.$REQUEST_URI);?>">sent to a friend</a>

2)PHP containing this form:
<form name="form1" register_globals=On method="post" action="recommend.php">
<input type="hidden" name="ref_url" value="$lienext">
Your Name:
<input type="text" name="yourname">


Your Email:
<input type="text" name="youremail">


Friends Email:
<input type="text" name="friendsemail">


Your Message:
<textarea name="yourmessage"></textarea>




<input type="submit" name="Submit2" value="Recommend">
</form>

3)PHP script:
<?
// Configuration of recipient and subject.

$recipient = "$friendsemail ";
$subject = "mySubject";
$mailheaders = "From: myEmail <$youremail>\n";
$mailheaders .= "Reply-To: <$youremail>";

$msg = "$yourname wrote:\n";
$msg .= "$yourmessage\n";
$msg .= "\n";
$msg .= $ref_url;

mail($recipient, $subject, $msg, $mailheaders) or die ("Couldn't send mail!");

?>

I appologise if I've made any 'school boy' errors - as I say this is all pretty damn new to me!

you can't specify "register_globals=On " like you did.

This is setup in php.ini and to change it requires you modify the webserver's configuration (php.ini) and relaunch it (or ask it to reload configuration with the -k switch for Apache, for instance)

Let's suppose you've register_globals=Off in php.ini (it's more common everyday day).

Then modify the second script as follows :

<?php
$lienext=$_GET['lienext'];
?>
<form name="form1" method="post" action="recommend.php">
<input type="hidden" name="ref_url" value="$lienext">
Your Name:
<input type="text" name="yourname">


Your Email:
<input type="text" name="youremail">


Friends Email:
<input type="text" name="friendsemail">


Your Message:
<textarea name="yourmessage"></textarea>




<input type="submit" name="Submit2" value="Recommend">
</form>

and the third one as follows :
<?
foreach($_POST as $var=>$value) ${$var}=$value; // yes, I know extract() does exist :D
// Configuration of recipient... etc
... etc

It's late here too :D Even later than for you . Not time to go to the pub, you alcooholic Brit (pleonasm) :D
By: VGR Date: 19/09/2003 18:58:00 English  Type : Comment
oh yes, true. You forgot to echo $lienext

I recommend the scripts as :

1)HTML with this link:
<a href="send_pagetest03.php?lienext="<?php echo urlencode($HTTP_HOST.$REQUEST_URI);?>">sent to a friend</a>

2)PHP containing this form:
<?php
$lienext=$_GET['lienext'];

echo <<<EOS

<form name="form1" method="post" action="recommend.php">
<input type="hidden" name="ref_url" value="$lienext">
Your Name:
<input type="text" name="yourname">


Your Email:
<input type="text" name="youremail">


Friends Email:
<input type="text" name="friendsemail">


Your Message:
<textarea name="yourmessage"></textarea>




<input type="submit" name="Submit2" value="Recommend">
</form>
EOS;
?>

3)PHP script:
<?
foreach($_POST as $var=>$value) ${$var}=$value; // yes, I know extract() does exist :D
// Configuration of recipient and subject.

$recipient = "$friendsemail ";
$subject = "mySubject";
$mailheaders = "From: myEmail <$youremail>\n";
$mailheaders .= "Reply-To: <$youremail>";

$msg = "$yourname wrote:\n";
$msg .= "$yourmessage\n";
$msg .= "\n";
$msg .= $ref_url;

mail($recipient, $subject, $msg, $mailheaders) or die ("Couldn't send mail!");

?>
By: tadpole03 Date: 19/09/2003 19:17:00 English  Type : Comment
Are you sure the initial line in the HTML is correct? I ask because when I use:
<a href="send_pagetest03.php?lienext="<?php echo urlencode($HTTP_HOST.$REQUEST_URI);?>">sent to a friend</a>
I get nothing as a link.

Where as when I use:
<a href="send_pagetest03.php?lienext=<?php echo urlencode($HTTP_HOST.$REQUEST_URI);?>">sent to a friend</a>

I get :<?php echo urlencode($HTTP_HOST.$REQUEST_URI);?> as the link in the mail.

I'm sure it's nearly there!
By: VGR Date: 19/09/2003 19:38:00 English  Type : Assist
No, leave as before, but you should perhaps use $_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI'] :D
By: tadpole03 Date: 19/09/2003 19:46:00 English  Type : Comment
I think the problem is coming from the HTML to the PHP with form, as after I leave step one the following is in the address bar:
<A HREF="http://www.stylefrogcreative.com/build/send_pagetest03.php?lienext=">http://www.stylefrogcreative.com/build/send_pagetest03.php?lienext=</a>

Shouldn't this contain the url?

Your server probably doesn't parse HTML for PHP code.
You can add the needed URL with JavaScript.

insted of:
<a href="send_pagetest03.php?lienext=<?php echo urlencode($HTTP_HOST.$REQUEST_URI);?>">sent to a friend</a>

do
<script language="JavaScript">
document.write ("<a href=\"send_pagetest03.php?lienext="+location.href+"\">sent to a friend</a>")
</script>
