My thought is there would be prior discussions on this. So here's my idea to find the priors.

after googling i have done the following but have encountered a error see below:
Warning: in_array() expects parameter 2 to be array, null given in /home/jktempla/public_html/sample/index.php on line 19

Playing

<input type="checkbox" name="hobbies[]" value="Playing" <?php echo (in_array('Playing',$hobbies)) ?'checked':'' ?> ><label>Playing</label><br/>
 <input type="checkbox" name="hobbies[]" value="Coding" <?php echo (in_array('Coding',$hobbies)) ?'checked':'' ?> ><label>Coding</label><br/>
 <input type="checkbox" name="hobbies[]" value="Reading" <?php echo (in_array('Reading',$hobbies)) ?'checked':'' ?> ><label>Reading</label><br/>
 <input type="checkbox" name="hobbies[]" value="Hacking" <?php echo (in_array('Hacking',$hobbies)) ?'checked':'' ?> ><label>Hacking</label><br/>
 <input type="checkbox" name="hobbies[]" value="Playing" <?php echo (in_array('Sleeping',$hobbies)) ?'checked':'' ?> ><label>Sleeping</label>

I can't guess your idea of what that code will do but the 2nd item is a string so that error would be correct.
Reference: http://php.net/manual/en/language.types.string.php
and http://php.net/manual/en/function.in-array.php

Maybe you declared it an array but I don't see your code to check here.

[janicemurby]

Heres the code hun

<?php

 if(!empty($_POST['hobbies'])) {

 if(empty($_POST['hobbies']) || count($_POST['hobbies']) < 2)
{
    $hobbies_error = "Please select at least 2 items for your hobbies";
    $error=true;
}
$hobbies = $_POST['hobbies'];

 //Loop through hobbies array to fetch individual hobby so that we can use them
 echo "<h2> You have selected: </h2>";
 foreach($_POST['hobbies'] as $hobby) {
 echo "<p>".$hobby ."</p>"; //Print all the hobbies

/* Alert hobbies using JS
$show = "<p>".$hobby ."</p>";
echo "<script type='text/javascript'>alert(\"Your Hobbies are: '$show'\");</script>";

 */
 }
 }
 else{
 echo "<b>Please Select at least One Hobby.</b>";
 }
 }
?>

Can't see where $hobby or $hobbies array is declared. What line is that on?
