Custom form tag generate input names

(@bhasic)

I have put a javascript number spinner in my CF7-form and I’m trying to make a custom form tag for it so that input names would generate automatic like mvr1, mvr2, mvr3… because I have multiple number inputs/spinners in the same form. I just cant get the number to appear in the inputs name. It just shows <input type=”text” name=”mvr[]” class=”in-num czr-focusable” value=”1″ readonly=””> in every field. What am I doing wrong?


add_action( 'wpcf7_init', 'custom_add_form_tag_spin' );

function custom_add_form_tag_spin() {
	wpcf7_add_form_tag( 'spin', 'custom_spin_form_tag_handler', array( 'name-attr' => true ));
}

function custom_spin_form_tag_handler( $tag ){
	return'<div class="num-block skin-7">
	<div class="num-in">
	<span class="minus dis">-</span>
	<input type="text" name="mvr[]" class="in-num" value="1" readonly=""
	<span class="plus">+</span>
	</div>
	</div>';
	{
		$name = $_POST['mvr'];
		foreach( $name as $key => $n ) {
			print $n;
		}
	}
}

Hi, bhasic, I’m another CF7 user.

What was your intent with the code block:
```
{
		$name = $_POST['mvr'];
		foreach( $name as $key => $n ) {
			print $n;
		}
	}
```
?

Since you return the string prior to that, this code doesn’t run.

That code block is supposed to generate numbers for mvr[] field names. I can’t get it to work no matter where I put the block. Does not work even when it’s run before return.

Hi, bhasic, if you want to increment the name attribute, work along the lines of this idea – increment the name attribute via PHP:
```
<input type="text" name="mvr<?php $name = $_POST['mvr'];
		foreach( $name as $key => $n ) {
			print $n;
		} ?>" class="in-num" value="1" readonly=""
```
Currently your code will output the same name attribute to each field because you are not manipulating it using PHP.
