reading value of html elements

[shane07]

Hello

Is it possible to read the value of the html element like hidden field and store in the server side variable without reloading the page?

I have a hidden field. I have to change the value of that field with the returned value of confirm dialog box using javascript which I did. But I have to store the value of the field in a php variable.

Or is there any way to read the value returned by the confirm dialog box using PHP?

 

Thanx

<?php
   $value = 0;
   if (!isset($_GET['value']) || !is_numeric($_GET['value'])) $value = intval($_GET['value']);
?><input type="hidden" name="foo" value="<?php echo $value; ?>" />

Do you mean that?

Lumio's method work, but you have to use JavaScript to redirect the user with the URL that contains the return value.

?><input type="hidden" name="foo" value="<?php echo $value; ?>" />

Do mean that?

 

I mean is it possible without reloading the page?

I need exactly the reverese process i.e. The value of the hidden field should be assigned to php variable which changes dynamically within a loop

 

for($i=1;$i<$num;$i++)
			{
			$destdir="../images/categories";
			$files1=scandir($destdir);
			//echo $files[$i]." ";
			$flag=0;
			foreach($files1 as $file)
			{
				if($file==$files[$i]&&$file!="Thumbs.db")
					{
					//echo $i." ".$file." ".$files[$i];
					if($files[$i]!="..")
						$flag=1;
				}

			}	
			if($flag==1)
				{
				?>
                    <script language="javascript"> 
				var ch=confirm("<?php echo $files[$i];?> already exists");
				if(ch==false)
					document.frm.hdn.value="false";
				else if(ch==true)
					document.frm.hdn.value="true";
				 </script>
                    <?php
				}
			else
				{if($files[$i]!="Thumbs.db")
				{
					if($files[$i]!="..")
						{copy($dir."/".$files[$i],"../images/categories/".$files[$i]);	
						unlink($dir."/".$files[$i]);
                                                        }

				}
			}
			}

Here is the code which I am working on

I want to copy the file only when it does not exist

So I have to something befor the copy function

[shane07]

Is there any way to run php scripts if user clicks on "yes" button of confirm dialog box otherwise do not run the php scripts?

I tried

<script language="javascript"> 
				var ch=confirm("<?php echo $file;?> already exists. Do you want to replace it?");
				if(ch==true) {
					<?php 	$copied=@copy($dir."/".$file,"../images/categories/".$file);
							if($copied==true)
							$count_files++;	 ?>
				}

But it didn't work. Instead the php scripts run despite of checking the condition.

Any advice will be appreciable

Thanx
