Hi there,
on my yardmaps website, if a user uploads an image taken with an iphone, and the exif data sets orientation to 1, the image is automatically rotated when put through the imagecopyresampled function.

If I take the same image, and strip out the exif data with photoshop (save as for web, no meta data), the image uploads correctly.

Is there any way to force imagecopyresampled to not rotate the image?

Thanks

Using php I have a dynamically filled select box with the names of images. How can I get an image box on my page and change upon selection?

Hi all,

I am dealing with an html page in which a dynamically created PNG image is shown with:

<img src="createchart.php">

The problem arises when users try to download the image since the default name that appears is just "createchart.php".
Is there any way to make the browser suggest something like "chart.png"?

Than you guys for your help,
Mam

This creates an image 1500x1500 pixels. But it creates it in black... how can i make it white.
And i have to use imagecreatetruecolor() not imagecreate().


<?php

$im = imagecreatetruecolor(1500,1500);


// Output the image to the browser
header('Content-type: image/jpg');

imagejpeg($im);
imagedestroy($im);
?>


Thanks!

Hi, I want to show one image for the new visitors of my website and another for the returning visitors. What I want to do is that after the visitor reload the page he will see another image instead of the first one.  

Currently, I insert a small thumbnail image at the begging of each row in a set of records from a mysql query. But that image is the same image for each record in that array.

Is there a way to conditionally change which image is used, based on a value either in that same table, or a related table.
See attached screenshot... and here's my current code....
Code: [Select]
<?php
$query = "select address from nvc";
$result = mysql_query($query);
while ($row = mysql_fetch_array($result, MYSQL_ASSOC))
{
$details='';
$details.='<li class="menu"><a href=detail.php?address='.(urlencode($row['address'])).'><img src="thumbs/house.png" /><span class="name">'.$row['city'].'</a>';
$details.='</li>';
echo($details);
}
?>

Thank you for any input.

I have a PHP script that uploads images to a folder on my server (attachments folder). Currently the folder sits within my webroot and is publicly accessible (I have to use chmod 777 due to permissions issue). So, I created the "attachments" folder outside of my webroot (so that it is not publicly accessible), but I do not know how to set the path in the PHP code to upload it to that "attachments" folder outside of the webroot. As you see in the snippet of PHP code below, the code currently uploads the the "attachments" folder within the www (webroot) directory. How do I make it upload to the "attachments" folder OUTSIDE of the www (webroot) directory?

foreach($files[$form] as $file){
         $str = $file[1];
         if (eval("if($str){return true;}")) {
            $_values[$file[0]] = $_FILES[$file[0]]["name"];
            $dirs = explode("/","attachments//");
            $cur_dir =".";
            foreach($dirs as $dir){
            $cur_dir = $cur_dir."/".$dir;
            if (!@opendir($cur_dir)) { mkdir($cur_dir, 0777);}}
            $_values[$file[0]."_real-name"] = "attachments/".date("YmdHis")."_".$_FILES[$file[0]]["name"]."_secure";
            copy($_FILES[$file[0]]["tmp_name"],$_values[$file[0]."_real-name"]);
            @unlink($_FILES[$file[0]]["tmp_name"]);
         }else{
          $flag=true;
          if ($_isdisplay) {
              //$ExtFltr = $file[2];
              //$FileSize = $file[4];
            if (!eval("if($file[2]){return true;}")){echo $file[3];}
            if (!eval("if($file[4]){return true;}")){echo $file[5];}
              $_ErrorList[] = $file[0];
          }
         }
      }

Hey guys!
I have the following php code that grabs variables (and the browsed image) from Flash.


//FLASH VARIABLES
$Name = $_POST['Name'];
$itemNumber = $_POST['itemNumber'];
$filename = $_FILES['Filedata']['name'];
$filetmpname = $_FILES['Filedata']['tmp_name'];
$fileType = $_FILES["Filedata"]["type"];
$fileSizeMB = ($_FILES["Filedata"]["size"] / 1024 / 1000);


list($filename, $extension) = explode('.', basename($_FILES['Filedata']['name']));
$filename = $Name;
$target = $filename . $itemNumber . "." . $extension;


// Place file on server, into the images folder
move_uploaded_file($_FILES['Filedata']['tmp_name'], "images/".$target);



This works perfect, but what I want to change is the width and height of the uploaded image.
Any ideas/suggestions on how this could be done?

Thanks in advance!!
Cheers!

I have a page where I want a success and a fail response. It's a contact page so, if they fill in all that's required, and send, a success "message" will pop up but if they send but for some reason, it fails, to display a fail "message".

What it does right now is the fail and success are constantly visible regardless.

So how do I make it display the corresponding message accordingly?

*Also how am I to make the text within the boxes invisible ? But that's lower priority

Hi, I need to create a secure API at work so that 2 systems can interact with each other and request data (json format). I need to use an API key for this but don't want to use an API key stored in a database, what is the best way to go about this?


I would like to use some sort of encryption algorithm and a white list of a few values to validate against once decrypted, is this safe and are there any algorithms I can use to generate my keys and white list?
