HTML Element Array, name=”something[]” or name=”something”?

PHP uses the square bracket syntax to convert form inputs into an array, so when you use name="education[]" you will get an array when you do this:

$educationValues = $_POST['education']; // Returns an array
print_r($educationValues); // Shows you all the values in the array

So for example:

<p><label>Please enter your most recent education<br>
    <input type="text" name="education[]">
</p>
<p><label>Please enter any previous education<br>
    <input type="text" name="education[]">
</p>
<p><label>Please enter any previous education<br>
    <input type="text" name="education[]">
</p>

Will give you all entered values inside of the $_POST['education'] array.

In JavaScript, it is more efficient to get the element by id…

document.getElementById("education1");

The id doesn’t have to match the name:

<p><label>Please enter your most recent education<br>
   <input type="text" name="education[]" id="education1">
</p>
