hi,

I have made an enquiry form in which I kept few hidden fields to capture the url parameters in them. The problem is those url parameters are not getting inserted in the hidden fields

This is how I did it all:

I made a snippet A,


<?php
$modx->setPlaceholder('ememail',$_GET['eme']);
$modx->setPlaceholder('keyword',$_GET['kw']);
$modx->setPlaceholder('eventurl',$_GET['url']);

$modx->setPlaceholder('emname',$_GET['emn']);
$modx->setPlaceholder('emmobile',$_GET['emm']);
$modx->setPlaceholder('title',$_GET['et']);
date_default_timezone_set('Asia/Calcutta');
$enqdate = date('D, d M Y, h:i:s A');
$modx->setPlaceholder('enqdate',$enqdate);
$modx->setPlaceholder('redirect',$_GET['redirect']);
?>

Then I made an enquiry form chunk with this code in it:


<input type="hidden" name="ememail" size="40"  value="[+ememail+]"  />
<input name="keyword" size="40" type="hidden" value="[+keyword+]" />
<input name="eventurl" size="40" type="hidden" value="[+eventurl+]"  />
<input name="emname" size="40" type="hidden" value="[+emname+]"/>
<input name="emmobile" size="40" type="hidden" value="[+emmobile+]" />
<input name="title" size="40" type="hidden" value="[+title+]"/>
<input name="enqdate" size="40" type="hidden" value="[+enqdate+]"  />
<input name="redirect" size="40" type="hidden" value="[+redirect+]"  />

The above code just a part of the enquiry form chunk.
Please help..
Thank You!

Hi
are you using a get method in your form ? (i.e <form > ) ?

Cheers

If you are using eForm, the tpl doesn't get processed by MODx; eForm does its own placeholder processing internally.

You'll need to use a function in your snippet to add the GET values to the $fields array, and use one of eForm's events. Then in the eForm tpl you can use the placeholders.

Can you please explain more? I mean is there an example of how to implement this code into a form?

I also would like to post the keyword in hidden field of a form.

Thanks in advance.

Here's a nice solution by sharkbait that I've been using successfully. You might need to read through from the beginning to piece together how it works:
