Two submit buttons using switch statementsq

**Schmit43** · 03-25-2012 02:52 AM

I have been trying for about a month now to get two submit buttons to work independently in PHP on the same page. I have found examples using text boxes but unfortunately my page has drop downs that use the _$POST array.

I for some reason cannot figure out how to code the switch case statement properly. Any ideas out there?

Here is the code for the PHP page:
(process.php)

Code:

<?php
error_reporting(E_ALL ^ E_NOTICE) ;
if($_POST['item']) 
  $item = $_POST['item']; 
 // print_r ($_POST['item']); 
else 
  $item = 2010; 
   print_r ($_POST[item]);
  
  if($_POST['item2']) 
  $item2= $_POST['item2']; 
else 
  $item2 = 2009; 
  ?>
  
  
  <?php

// branch on the basis of 'Select1' value 
switch ($_POST['item']) {
      // if Select1 => add
      case 'Submit':
       //     print_r $_POST['Select1']);
	   $url = "<img src='/WXRECORDS/images/{$item}.png' />"; 
            break;

      // if Select1 => subtract
      case 'Submit2':
         //   print_r $_POST['Select1']);
		 $url = "<img src='/WXRECORDS/images/{$item2}.png' />"; 
            break;
    
}

?>
  
  <?php
  
 
$url = "<img src='/WXRECORDS/images/{$item}.png' />"; 

include_once('portland.html');
?>

And here is the code for the HTML page
(portland.html)

Code:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">

      <link href="stylesheets/public.css" rel="stylesheet" type="text/css" >
   </head>
   <body style="height: 53px; color: #FFFFFF; background-color: #000000;">
      <form  action="process.php" method="post">
         <div id="banner" class="banner">Portland Oregon Climate Data </div>
         <div id="header" class="header" style="height: 35px; width: 300px" align="center">
      

      <!DROP DOWN #1>
			<select name="item" style="width: 55px">
                <?php for($i=2010; $i>=2006; $i--){?>
                  <option value="<?php echo $i?>" <?php if($i==$_POST['item'])
				  echo 'selected="selected"'?>><?php echo $i?></option>
                <?php }?>
            </select>   &nbsp 
			<!BUTTON #1>
            <input name="Submit1" type="submit" value="submit" style="height: 28px" />
			
			
			
	  <!DROP DOWN #2>
			<select name="item2" style="width: 65px">
                <?php for($i=2010; $i>=2006; $i--){?>
                  <option value="<?php echo $i?>" <?php if($i==$_POST['item2'])
				  echo 'selected="selected"'?>><?php echo $i?></option>
                <?php }?>
				<!BUTTON #2>
            <input name="Submit2" type="submit" value="submit" style="height: 28px" />
			
            </select>   </div>
		
		 <br />
		 
      </form>      <div id="content" align="center" class="content"><?php echo $url ?></div>
   </body>
</html>

I must admit I am embarrassed that I still have not figured out this code. I dont know why its so difficult for me. Tons of tutorials have not done the trick.

haven't tested the code, but one thing you surely got wrong are the brackets and a condition

Code:

	error_reporting(E_ALL ^ E_NOTICE) ;
	if($_POST['item']){
		$item = $_POST['item']; 
		// print_r ($_POST['item']); 
	}
	elseif(...){
		$item = 2010; 
		print_r ($_POST[item]);

		if($_POST['item2']) 
		$item2= $_POST['item2']; 
	}
	else{
		$item2 = 2009; 
	}

I tried to construct the If-then-else statement to print_r the $_POST array for these two buttons. The braces are matched up but I still get an error on line 17

Code:

<?php
error_reporting(E_ALL ^ E_NOTICE) ;
//If button 1 is clicked
if($_POST['item']) {
  $item = $_POST['item']; 
  print_r ($_POST['item']); 
 }
else if ($_POST['item']){
  $item = 2010; 
   $item = $_POST['item']; 
  print_r ($_POST['item']); 
   }
  //if button 2 is clicked
  if($_POST['item2']) {
  $item2= $_POST['item2']; 
    print_r ($_POST['item2'])
  }
else {
  $item2 = 2009;
    $item2 = $_POST['item2']; 
  print_r ($_POST['item2']);
}  
  ?>

you forgot a semicolon

Code:

  //if button 2 is clicked
  if($_POST['item2']) {
  $item2= $_POST['item2']; 
    print_r ($_POST['item2']);
  }
else {

Thank you.. I make so many amateur mistakes.
So now I am trying to use a switch statement. I want to make either button respond independently. One button is called 'sumbit' and the other is called 'submit2'. Obviously my inevitable goal here is to load images from the currently selected drop down. Any ideas?

Code:

// branch on the basis of 'Select1' value 
switch ($_POST['item']) {
      // if Select1 => add
      case 'Submit':
       //     print_r $_POST['Select1']);
	   $url = "<img src='/WXRECORDS/images/{$item}.png' />"; 
            break;

      // if Select1 => subtract
      case 'Submit2':
         //   print_r $_POST['Select1']);
		 $url = "<img src='/WXRECORDS/images/{$item2}.png' />"; 
            break;
   
}

?>

Here is what you are looking for

PHP Code:


if($_POST['Submit1']){

    $url = "<img src='/WXRECORDS/images/{$_POST['item']}.png' />"; 

}elseif($_POST['Submit2']){

    $url = "<img src='/WXRECORDS/images/{$_POST['item2']}.png' />"; 

}else{

    $url = "<img src='/WXRECORDS/images/default_image.png' />"; 

}
