如何将文本框在php中保存为数组？

Question

Is there anyway to save a textboxs as an array similar to how multiple checkboxs can be saved as an array? When you save multiple checkboxs to an array the value only comes up in the array when the checkbox has a check in it. Is this the same with textboxs? Do they only have value when they're not empty?

I'm trying to save these textboxs as an array (I only took the part of the form that you all need to see)

<form action="formemail.php" method="POST" name="rcr">
<td><input type="text" name="desc[]" id="desc"></td>
<td><input type="text" name="desc[]" id="desc"></td>
<td><input type="text" name="desc[]" id="desc"></td>
<td><input type="text" name="desc[]" id="desc"></td>
<td><input type="submit" name="sendwork" id="sendwork" value="Send Work Order"></td>

</form>

In the next page I'm trying to take these values and just output them in a simple way (later I'm going to be adding them to an email using foreach if I can)..... below is formemail.php

<?php
$description = $_POST["desc"];
echo $description[0];
echo $description[1];
?>

I can't get anything to echo for the life of me. And I'm not sure what I'm doing wrong.

Answer 1

tried ?

   if(  isset( $_POST["desc[]"] )  ) echo "is set ; )";

btw. same multiple id's can cause you problems if you work with JS/JQuery.

Answer 2

Try to use foreach and test submitted values:

foreach($_POST['desc'] as $post)
{
    echo !empty($post) ? $post.'<br />' : 'An empty value.<br />';
}
