Checking if multidimensional array is empty?

Posted on 16th Feb 2014 07:03 pm by admin

I have a for with multiple test input fields. Specifically the user submits multiple names and ages. The form is submitted using the POST method. Here is a code snippet:

Code:
<form action = {$_SERVER['PHP_SELF']} method = 'post' >

for($i=1; $i<=10; $i++){

<input type = 'text' name = 'name[]' size ='25' maxlength = '50' />
<input type = 'text' name = 'age[]' size ='25' maxlength = '50' />

}

<input type="submit" />

</form>

I want to check if the user clicks submits without entering values in the text fields.

I have tried this:

Code: if(empty($_POST['name']) && empty($_POST['age'])){

echo "All the entries were blank, please enter name(s) and age(s) on the left and click submit. Thank you.";

}

However, this doesn't parse as "true" when I click submit with the fields empty.

Is it not possible to use "empty()" with arrays and/or multidimensional arrays?
