from $_GET['checkTitle'] into an array

I'm trying to figure out how to get the $_GET['checkTitle'.$b] into an array. $b indicates that they are numbered.

for($b=0; $b<66;$b++){
	if(!empty($_GET['checkTitle'.$b])){
	$checkTitleArr=Array($_GET['checkTitle'.$b]);
	print_r($checkTitleArr);
		//$sql.= " AND";
		//$sql.= " OR";
		//$sql.= " book_title='".$_GET['checkTitle'.$b]."'";
	}
}

PHP:

What I'm getting so far is:

When 2 books are checked in the <form>.

 

You are looping 65 times because u have 65 checkboxes?

Try this, this is the basic idea.

if (replace_with_your_submitted_check) {

//unset input type="submit" name="submit" if necessary
//unset($_POST['submit']);

//if your form contain checkboxes only (beside submit button)
$i = 0; // will be used for loop
  foreach ($_POST as $checkbox) {
    $checkTitleArr[$i] = $checkbox ;
    $i++;
  }

// test result
print_r($checkTitleArr);


} // close your if (submitted)

PHP:

 

I don't understand this:
replace_with_your_submitted_check

 

Your script must have a part where u check if the form is submitted right? thats the part.

an example: if( isset( $_POST['submit']) ) {

if the form is submitted to a different file, you can skip that.

 

Do you have 66 checkboxes? And you want to go through them one by one? Then use this:

<input type"checkbox" name=checkboxes[item1] value="1 "/>
<input type"checkbox" name=checkboxes[item2] value="1 "/>
<input type"checkbox" name=checkboxes[item3] value="1 "/>
<input type"checkbox" name=checkboxes[item4] value="1 "/>

HTML:

$array_of_checkboxes=$_POST['checkboxes']
foreach($array_of_checkboxes as $name=>$value)
{
echo $name.' : '.$value;// example: item1: 1
}

PHP:

 

What if I have an ajax code?

	checkTheTitle=document.getElementsByName('checkTitle[]');
	//txt="";
	for (i=0;i<checkTheTitle.length;++ i)
	  {
	  if (checkTheTitle[i].checked)
		{
		getKeyURL=getKeyURL + "&checkTitle=" + checkTheTitle[i].value;
		}
	  }

Code (markup):

what happens to the getElementsByName('checkTitle[]');? Does it stay as is or change somehow?
