Hi. I have a form with input type button:

HTML
<form method="post" action="index.php" id="addForm" name="addForm" enctype="multipart/form-data">
      ...
      <input type="button" class="btns" value="Add" id="submitAdd" name="submitAdd"/>
</form>


This is my jQuery code that I use for form validation and submitting form:

JavaScript
$('#submitAdd').click(function (){
	// validating input and if everything is right submitting the form	
	$('#addForm').submit();
});


Now if I want to check if button submitAdd is empty nothing happens:
PHP
if(!empty($_POST('submitAdd'))) //this is always false; if I put true script is normally done


What I have tried:

I can't put input type submit instead button because form is then automatically submitted. How can I avoid this situation? Please help.

Any help?

1 solution

First, the form:
HTML
<!DOCTYPE html>
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.4/jquery.min.js"></script>
</head>
<body>
<form method="post" action="index.php" id="addForm" name="addForm" enctype="multipart/form-data">
      <!-- other input types -->
      <input type="submit" class="btns" value="Add" id="submitAdd" name="submitAdd">
</form>
<script>
$('#addForm').submit(function (){
	// validating input and if everything is right submitting the form	
	//$('#addForm').submit();
    valid = false; // true or false based on the validation outcome
	if(valid) {
		return true; // proceed to submit
	
	} else {
		return false; // abort submission
	}

});
</script>
</body>
</html>

Next, the PHP side, it should be [] not (), i.e.
$_POST["submitAdd"]
