Newbie with PHP issue

Ok, so I'm teaching myself a bit of PHP (Webmonkey) to ease the efforts of multiple static pages. I understood how to do the "transfer" of the variable input by a user into a text box, to a new PHP page and "printed" into the HTML .
I tried to take it a step further and send a coding variable to a page and have the variable be the file name for an image(thumbnails to full images). In the body of the first page I had:

Code:

<form action="newPage.php" method=post>
          <?php
          $design="des01.png"
          ?>

          <input type="image" src="thumb.jpg" name=submit></form>

Then in the new page:

Code:

<?php
                print ("<img src=\"designs/$design\">"
                ?>

The goal was to have the outcome as <img src="designs/des01.png">

I got the new page with out the image. The directory was there but it doesn't seem to be getting the value of the variable (<img src="designs/">). Can you tell me where I'm missing whatever it is that keeps the information from being sent/received? Maybe the form is not neccessary?

Thanks (the actual code is not in front of me right now, but I'm fairly certain it's what I tried, well, one of the many variations). Any help is appreciated.

hi,

the $design is not assigned as a global variable, so it wont get posted from page to page, you can however create a hidden field, with the value of $design and $_Post['HiddenFieldName']; on the other page.

try this

Code:

 page1:
 <form action="newPage.php" method=post>
 		  <?php
 		  $design="des01.png"
 		  ?>
 
 	<input type="hidden" name="design" value="<?echo $design;?>">
 		  <input type="image" src="thumb.jpg" name=submit>
 </form>
 
 ---newPage.php
 
 $design = $_POST['design'];
 
 print ("<img src=""designs/".$design."">")

hope this helps

the form doesn't post data to the next page unless it is in an input field. You could do that like this:

Code:

 <form action="newPage.php" method="post">
 <?php $design="des01.png"; ?>
 <input type="hidden" name="design" value="<?=$design;?>" />
 <input type="image" src="thumb.jpg" name="submit" />
 </form>

then on the next page:

Code:

 <?php
 echo ("<img src=\"designs/" . $_POST["design"] . "\">";
 ?>

good luck!

Hmmm, neither work. Maybe I need to keep reading, but hopefully I won't get hung up. Just seemed simple enough and both codes look like it makes sense. The second page just comes up blank (white screen).

I did that, and there was nothing between the body tags. I did, however, get it to work. I mixed what I was doing originally, and what you suggested with the hidden input. First page code is:

Code:

<form action="/designs/des01.php" method="post">
					<?php 
						$design="des12.jpg"
					 ?>
					 <?php 
						$label="Design 12"
					 ?>
					 	<input type="hidden" name="label" value="<?=$label;?>" /> 
						<input type="hidden" name="design" value="<?=$design;?>" /> 
 					<input name=submit type="image" src="images28/des12.jpg" width="175" height="160">
				</form>

and the receiving page:

Code:

<?php
			  	print $label
			  ?>
			  </p>
	    <br><br><br><center>
		<?php
 				print ("<img src=\"$design\">")
 		?>

I noticed when I tried to put set the two variables within the same PHP tags, I got the white screen. You can't just stick them all in there like other languages???

Thanks for the assistance. Can't wait to keep moving forward with this stuff!
