[kathir]

Hello Frieds,

I have problem with simple class in php. Please Help.

This is my form code.

<form name="form1" action="ex1_exec.php" method="POST" />
<input type="text" name="val1" />
<input type="submit" name="submit" value="Submit"  />
</form>

and,

the ex1_exec.php file code is,

<?php
 public $val1=$_POST['val1'];
 class tempclass
 { 
    return $this->val1+5;
 }	
  $obj=new tempclass($val1);
  echo $obj->val1;
?>

When try to run those codes, i get only empty page.

Please Help for this problem.

Can we see it where you added the error checking?

Notes:

 

1 - you defined a public var called val1 but it is not part of your class.  Correct?

2 - you defined the class and included an executable line. I do not know how that fits since it is not part of a constructor.  Of course, I'm not a big OO guy.  Also - you have no methods for this class.

3 -  you attempt to display a property of the class that is not defined for the class.  Got to be an error.

Classes don't really work that way in terms of the direct return statement.

 

Your class should look more like this:

class tempclass { 

	public $val1;

	function __construct($my_var) {
		$this->val1 = $my_var+5;
	}
}

but really it looks like you want a function more than a class

function my_func($my_var) {
	return $my_var+5;
}
