Contact Form 7 Input Fields Values as PHP Get-Viarables

Tylor,

I’ve written a hack for this as I had the same requirement and could not find a solution anywhere! I’m not a WordPress expert so hopefully someone who is can take this and refine it. It does work though ??

in plugins/contact-form-7/modules open up text.php.

find the line:
$value = $values[0]; (about line 73)

replace with:

$match = strpos($values[0], 'GET_');

if ($match === false) {
	$value = $values[0];
} else {
	$values[0] = str_replace('GET_', '', $values[0]);
	if (isset($_GET[$values[0]])) {
		$value = $_GET[$values[0]];
	}
}

Save the file.

In the contact form admin area, when you have a field that requires a GET var to appear insert ‘GET_’ directly before the variable name – ie;

[text your-name "GET_ref"]

If the GET var exists it will appear otherwise the field will be left blank!

There’s no support with this but I hope it solves your problem until a better option becomes available ??

Thanks,
Matt

This works great – Thanks Matt!

Any idea how to get something working on a select statement?

[select* VARIABLE include_blank "one" "two" "three" "four" "GET_VARIABLE"]

In the case above the GET_VARIABLE ends up being treated as one of the select options. If you put it prior to the include_blank it breaks the select box.

Thanks Matt,that works great and put me onto the track of adapting this to my own wishes. I needed to pass parameters to the form but could not use the URL; what I’ve done below is slightly adapt your code so I can pass parameters to text fields using WP’s ‘Custom Fields’.

What I do is add a custom field to a post, let’s say with the name “Itin” (for Itinerary) where the key will hold the Itinerary-code I want to pass to the form. Then, I add “CF_fieldname” to the text-field definition in the contact form. So for instance, to get the ‘Itin’ custom field into the ‘itin-code’ textfield, I can use:

Itinerary code: [text itin-code 30/30 "CF_Itin"]

That way, any custom field can be put in any text field. The adapted code (replacing, as above: $value = $values[0]; with:

$match = strpos($values[0], 'CF_');
		if ($match === false) {
			$value = $values[0];
		} else {
			global $post, $key;
			$values[0] = str_replace('CF_', '', $values[0]);
			$key = $values[0];
			$value = get_post_meta($post->ID, $key, true);

		}
</code></p>

Though in no way beautiful (not a PHP programmer) it works, and might be useful to others.

im trying to get this to work with the [select] dropdown box, instead of text field, but it doesnt seem to work. Anyone can help?

Really could use a mod to get on of the values in dropdown to be preselected according to custom field value (if exists and/or matches one)
Thanks

A good solution is to use “Id” in Contact Form 7 values.

1. Set up an html form that will pass variables

<form action="URL_TO_CONTACT_FORM_7_PAGE" method="get">
<select name="YOUR_VALUE" id="YOUR_VALUE">
<option value="1">1</option>
<option value="2">2</option>
<option value="3">3</option>
</select>
</form>

2 Set up a Contact Form 7 element with “id”:

[select YOUR_VALUE id:YOUR_VALUE
"1"
"2"
"3"
]

3. Use javascript on the page, and php (use exec php plugin or similar to execute php code)

[CONTACT FORM 7 TAG]

<script type="text/javascript">
 document.getElementById('YOUR_VALUE').value = "<?php echo $_GET['YOUR_VALUE'];?>";
</script>

@mrchambers
your hack would be the solution for my problems. The only problem I have right now: in my file “text.php” is no line like the one you posted:

$value = $values[0]; (about line 73)

So what to replace now? ?? What version of Contact Form 7 do you use? I downloaded the latest 2.2 last updated 2010-3-22. I am using WordPress 2.9.2.

Thanks for your help
Floyd

@floydman

The line you would replace be around line 80 looks like this:

$value = isset( $values[0] ) ? $values[0] : '';

@mrchambers –

Excellent! Your solutions works perfectly! Thank you for posting!

@mrchambers,

Would you know how to pass variables to each submission that will let me know visitor’s cookie/session information, specifically – how did they originally get to the site? I am trying to track conversion by source. Thank you.

Hello, I am getting parse errors when I try mrchambers fix. Any ideas? Thanks!

I’ve updated to the latest version of Contact Form 7.
The fix mrchambers posted no longer works

<ahem> I apologize. After updating Contact Form 7, you have to “reapply” the fix in text.php

@mrchambers – thanks for the advice. It’s really worked.
I made some small changes additionally to yours, to allow hidden fields. on text.php:

add at top:
wpcf7_add_shortcode( 'hidden', 'wpcf7_text_shortcode_handler', true );

there is need to make a change in two “if” statements at lines 36 and 39, so the whole part will look like the following:

if ( 'email' == $type || 'email*' == $type || 'hidden' == $type)
		$class_att .= ' wpcf7-validates-as-email';

	if ( 'text*' == $type || 'email*' == $type || 'hidden' == $type)
		$class_att .= ' wpcf7-validates-as-required';

and finally, the line:
$html = '<input type="text" name="' . $name . '" value="' . esc_attr( $value ) . '"' . $atts . ' />';

change into:

if ($type == 'hidden'){
	   $html = '<input type="hidden" name="' . $name . '" value="' . esc_attr( $value ) . '"' . $atts . ' />';
    }   else {
       $html = '<input type="text" name="' . $name . '" value="' . esc_attr( $value ) . '"' . $atts . ' />';
    }

now you just add to your form the following line:
[hidden get-field-name "GET_fieldname"]

That’s it. hope it helps
