• PHP | Get input name through $_POST[] 8 answers

Using PHP Codeigniter, I have a form with multiple numeric inputs, each with unique name:

<td><input type="number" style= 'width: 40px' name="order<?php echo $bannerId?>" value="<?php echo $banner->b_order; ?>"</td>

I can access the field value using:

$_POST['order'];

but is there a way in PHP to access the name attribute itself, instead of the value? So in the controller I can use the $bannerId variable echoed in the form.

</div>

Answer 1

Using array keys you could get all the 'names' and then loop over them?

array_keys($_POST)
