14,268 PointsHow do I receive these form results?
I've been building a form where users select whether they want an item via checkbox and can add notes if they have any special requests. I've gone through "Build a Simple PHP Application" a couple times, but translating from how the contact form was made to what I need for this project has been difficult.
The mock-up can be viewed here: http://flatscreensigns.com/content-form.php
The list items are stored in associative arrays and are displayed using a foreach loop.
$brandings = array();
$brandings["VSS_br_welcome"] = array(
"title" => "Welcome Message",
"img" => "/img/VSS_br_welcome.jpg",
"select" => "on" <<(this is for pre-populating a checkbox because we recommend it)
);
<ul class="group grid12">
<?php foreach($brandings as $branding) { ?>
<li class="item grid3">
<h3 class="item_title"><?php echo $branding["title"]; ?></h3>
<img src="<?php echo $branding["img"]; ?>" alt="<?php echo $branding["title"]; ?>" class="item_img">
<div class="selector_cont">
<input type="checkbox" name="selector_<?php echo $branding["title"]; ?>" id="selector_<?php echo $branding["title"]; ?>" <?php if($branding["select"] == "on" ) {echo 'checked="checked"'; }?>>
<label for="selector_<?php echo $branding["title"]; ?>" id="selector">select</label>
</div>
<textarea name="notes_<?php echo $branding["title"]; ?>" id="notes_<?php echo $branding["title"]; ?>" class="notes"></textarea>
</li>
<?php } ?>
</ul>
I'd really appreciate some guidance on what is needed for receiving the results from the form. If an item is selected/checked, I'd like the results to include its title from the array, img from the array, and, if there are any, the notes associated.
I've tried a few things but the results I get are never what I expect. I don't think I understand how to interact with the arrays properly.

<form
method="GET" //define how information gets send
action="pagename.php" //define where information is sent to.
>
//enter inputs checkboxes, textareas...
</form>
I dont have time to give you a detailed help instruction at the moment, ill check on this post later.

14,268 PointsI apologize, I do have a form tag in my code, I just didn't paste it into here. Now that you mention it though, why would I use "GET" as my method instead of "POST"?

I'd recommend you check out my two sets of videos on handling form submissions in PHP:
The contact form uses post, but my next videos to be released with look at a get form.

14,268 PointsHI Randy,
I've been through the videos you suggested a couple times and I'm still confused. In the videos, you create variables for each item in the $_POST array and relate them to the form field.
$name = $_POST["name"];
$email= $_POST["email"];
$message= $_POST["message"];
But since my form fields are created using a foreach loop and associative arrays, how can I create variables for the $_POST array?

Treehouse Guest TeacherWhen you first receive the post submission, put this code in place:
var_dump($_POST);
exit;
This will show you all the information about the $_POST array at that point, including all the elements it contains.
Does that help?
