PHP post variables titles - php

Question

I am wondering how I can extract the title variable from my forms posted fields array.
I know $_POST['name'] is the field name but can I do something like $_POST[title] to get the title?
I ask because I have a dynamic form with variable lengths. The dynamics is group_one contains 5 fields, group_two contains 12 fields, group_three contains 2 fields for example.
I am hoping to loop through these groups and post the title of the form field to a column in a DB and its value. Any help appreciated with understanding if I can use the 'title' variable in the form field element.
<input type="radio" name="txtGroupOne[]" id="txtDogAtPremisesYes" value="Yes" title="Dog at premises" />Yes
<input type="radio" name="txtGroupOne[]" id="txtDogAtPremisesNo" value="No" title="Dog at premises" />No
<input type="text" name="txtGroupOne[]" id="txtNextOfKinName" title="Next of kin name" />
<input type="text" name="txtGroupOne[]" id="txtNextOfKinContact" title="Next of kin contact" />

Answer 1

No, only the name="x" attribute is sent by default in an HTML Form. title="x" is not sent. You can technically get around it with some crazy Javascript and an Ajax POST, but I would avoid that if I were you.
What do you want the title sent to your server side for? There surely probably a better alternative to achieve your goal.

You can add hidden field to each of fields that need titles to be sent to server besides their values.
<input type="radio" name="txtGroupOne[]" id="txtDogAtPremisesYes" value="Yes" />
<input type="hidden" name="txtGroupOneTitles[]" value="Dog at premises" >
<input type="radio" name="txtGroupOne[]" id="txtDogAtPremisesNo" value="No" />
<input type="hidden" name="txtGroupOneTitles[]" value="Dog at premises" >
<input type="text" name="txtGroupOne[]" id="txtNextOfKinName" />
<input type="hidden" name="txtGroupOneTitles[]" value="Next of kin name" >
<input type="text" name="txtGroupOne[]" id="txtNextOfKinContact" />
<input type="hidden" name="txtGroupOneTitles[]" value="Next of kin contact" >

You can do something like this:
foreach($_POST as $form_var){
// Compile your code here, etc.
}
Anything that does not have a "name" attribute in your form will not be part of the $_POST array.
ie,
<input type='text' id='bar'>
<input type='text' name='foo' id='foo'>
Only $_POST['foo'] would exist.
Misread the question slightly, but you could also prepend your input names to include the "group title" upon generation.
<input type='text' name='title1_foo' id='title1_foo'>
Then you can manipulate the information you want from the $_POST loop.
