PHP - Header Error To Resize Image??

I did a tutorial on uploading a profile pic and also did a tutorial on an image re-size class. The only thing is the tutorial on the re-size class is done without using a form which is pointless. Can someone help me integrate this into the profile pic tutorial? Here's a link to the re-size tutorial.

Hi,

Im rather new to php and really unable to get the above to work. Everything works apart from the image being resized. File is uploaded, and the image name is printed into the SQL database. But i cant for the life of me get the image to go to 300x200? If you could help me i would be very grateful

My code for the form processing page is attached. Ive put a few line breaks into the code as to where i think is the issue. I just cant seem to resize the image. Does the image resize need to come before the part it writes the image to the server or can this be done afterwards? Please help.

P.S - Thanks in advance

I am having a lot of trouble finding material to help me with this problem. I am using cakephp 1.2. What i want to be able to do is give users the ability to upload an avatar.

For form is quite basic (takes the data and updates the corresponding record in the database) but I need to add in a file upload form object so the user can pick an image then i my code to be able to take that image and save it in multiple sizes and finally to save the image name and extension (ex: image.jpg) in to the database table.

If anyone can help me with this it would be such a massive help.

Hi,

I have an interface where the user picks an image to upload, it then uploads the original (big) image.

That same image then appears but at a reduced size of 150px max height or width, the size is defined in the img tag using height="XX" width ="XX", so it is the same image file, just with its dimensions set in the html.

The user then drags a div over the image to crop it.

The problem I am having is getting the reference image crop dimensions to translate to the actual full size image.

Have attached an image of what the result is.

What formula do I need to get it to translate to the bigger image properly?

Here is my code:

if($_GET['mode'] == 'imageupload')
{

$imgNumber = $_GET['img'] ;

$fileName = strtolower($_FILES["setFile$imgNumber"]['name']) ;

$ext = explode('.', $fileName) ;
if($ext[1] != 'jpg' && $ext[1] != 'JPG' && $ext[1] != 'jpeg')
{
echo "<span class='iFOutput'>Can only accept JPG images.<br /><br /> The image you tried to upload was '" . $ext[1] . "'.</span>" ;
exit() ;
}

$tmpName = $_FILES["setFile$imgNumber"]['tmp_name'] ;

move_uploaded_file($tmpName, '../uploads/' . $fileName) ;

$sizeInfo = getimagesize('../uploads/' . $fileName) ;

$resizedArray = imageResize($sizeInfo[0], $sizeInfo[1], 204) ;

$finalImageSrc = '../uploads/' . $fileName ;

echo '<img id="image' . $imgNumber . '" src="' . $finalImageSrc . '" width="' . $resizedArray[0] . '" height="' . $resizedArray[1] . '" />' ; // SCALED IMAGE FOR CROPPING INTERFACE

}
elseif($_GET['mode'] == 'imagecrop')
{
$imgSrc = $_POST['imagePath'.$_GET['img']] ;

$thisX1 = $_POST['image' . $_GET['img'] . 'X1'] ;
$thisY1 = $_POST['image' . $_GET['img'] . 'Y1'] ;
$thisX2 = $_POST['image' . $_GET['img'] . 'X2'] ;
$thisY2 = $_POST['image' . $_GET['img'] . 'Y2'] ;

$original = imagecreatefromjpeg($imgSrc) ;

list($width, $height) = getimagesize($imgSrc) ;

if ($width > $height)
{
$ratio = (150 / $width);
}
else
{
$ratio = (150 / $height);
}
echo $ratio ;
$thumbCanvas = imagecreatetruecolor(150, 150) ;
$thisX1 = round($thisX1/$ratio) ;
$thisY1 = round($thisY1/$ratio) ;

imagecopyresampled($thumbCanvas, $original, 0, 0, $thisX1, $thisY1, 150, 150, $width, $height) ;

imagejpeg($thumbCanvas, '../uploads/thumbnail.jpg') ;

echo '<img id="image' . $_GET['img'] . '" src="' . '../uploads/thumbnail.jpg' . '" />' ;

Hello,

I use this code to resize images:


<?php
function makeresize($dir,$pic,$n,$t){
  @list($width, $height, $type, $attr) = @getimagesize($pic);
  $max_w = 700;
  $max_h = 500;
  $ratio = @min($max_w/$width,$max_h/$height);

  
  if ($ratio < 1){

    $w = @floor($ratio*$width);
    $h = @floor($ratio*$height);

    
    $thumb = @imagecreatetruecolor($w,$h);
    if ($t == 'image/jpeg'){$temp = @imagecreatefromjpeg($pic);}
    elseif ($t == 'image/gif'){$temp = @imagecreatefromgif($pic);}
    elseif ($t == 'image/png'){$temp = @imagecreatefrompng($pic);}
   

  
    @imagecopyresampled($thumb,$temp,0,0,0,0,$w,$h,$width,$height);
    if ($t == 'image/jpeg'){@imagejpeg($thumb,"$dir/".$n, 100);}
    elseif ($t == 'image/gif'){@imagegif($thumb,"$dir/".$n, 100);}
    elseif ($t == 'image/png'){@imagepng($thumb,"$dir/".$n, 8);}
  }
}
?>






the  code that calls the function above is:


 $tipi_consentiti = array("image/gif","image/jpeg","image/png","image/pjpeg");

    // form data
    $titolo = @addslashes($_POST['titolo']);
    $descrizione = @addslashes($_POST['descrizione']);
    $nome = @addslashes($_FILES['imagefile']['name']);
    $path = $carfoto_user . stripslashes($nome);
    $tipo = @addslashes($_FILES['imagefile']['type']);   

............

  
  if ((@in_array($_FILES['imagefile']['type'], $tipi_consentiti))&& ($_FILES["imagefile"]["size"] < 2200000)){
    // copio il file nella cartella delle immagini
    @copy ($_FILES['imagefile']['tmp_name'], $carfoto_user . $nome);

  $nomenew = $t."_".$nome;
 
    

@makeresize($carfoto_user,$path,$nomenew,$tipo);
    
  
    
    unlink($carfoto_user.$nome); 




well.

everything works fine, but  now I want to paste the resized image produced
on another image that has a fixed size.
It is necessary for javascript gallery output (if the image is too small).
How can I change the above code to do this.
Can you help me?

but gave me error.

I'm trying to find a good function that allows me to resize an image and specify the paths, the dimensions, and the quality about the image.  Does anyone have any suggestions? Thanks

I have been searching since past 3 days and came across many functions on php.net and other sites but i am unable to get it to work. Because in my case already uploaded image names are coming out of database through a while loop. So not sure how to integrate those functions here.

Its a very simple process, images are uploaded and stored in a gallery folder and their names are stored in database.

Then these images are displayed through while loop as follows


<?php
$sql = "SELECT * FROM gallery";
$result = @mysql_query($sql) or die(mysql_error());
while($rows = @mysql_fetch_array($result)){
$file = $rows['filename'];
?>
<img src="gallery/<?php echo $file; ?>" border="0" />
<br />
<?php
}
?>


But image dimension can be random so i want it to show in a fixed size of 150x150. I am looking for a very simple method to make that happen. Please help.

How can I resize an image that i'm showing and rather than saving it, just output the file?

And would this vary if I was to be first calling the image through AJAX?

What I want to do is to upload an image, find out what the size is and then make the height=377, and keep with width at the same ratio.

this is my upload code:

Code: [Select]
<?php
error_reporting(0);

mysql_connect("localhost","root","") or die(mysql_error());
mysql_select_db("myDB") or die(mysql_error());

$picture = $_FILES['image']['tmp_name'];
$brand = $det['pro_name'];
$year = $det['pro_vint'];
$story = $det['pro_story'];
$description = $det['pro_desc'];
$why = $det['pro_why'];
$intensity = $det['F12'];
$body = $det['F11'];
$sweet = $det['F8'];
$acid = $det['F9'];
$oak = $det['F10'];
$lcbo = $det['lcbo_num'];
$size = $det['pro_size'];
$btl = $det['pro_btl'];
$price = $det['pro_price'];
$lto = $det['F7'];
$audio = $det['wineAudio'];

if(!isset($picture))
echo "";
else
{
$image = addslashes(file_get_contents($_FILES['image']['tmp_name']));
$image_name = addslashes($_FILES['image']['name']);
$image_size = getimagesize($_FILES['image']['tmp_name']);

list($width, $height, $type, $attr) = getimagesize($_FILES['image']['tmp_name']);

if($height != $width * 1.5 ){
   echo "Image does not meet requirements";
}else{

if($image_size==FALSE)
echo "This is not an Image";
else{
if(!$insert = mysql_query ("UPDATE `phpmy1_vincastweb_com`.`Sheet1` SET `image_name` = '".$image_name."', image='".$image."' WHERE  `pro_id` ='".$id."'"))
echo "Problem Uploading Image.";
else{
$lastid = mysql_insert_id();
echo "Image Uploaded!<p />".$text."<p /><p /> Your Image:<p />";
$lastid = $id;
echo "<img src='get_2.php?Product=$lastid' width='250' height='320' /><br />Click <a href='Agency/product3.php?Product=".$id."' target='_blank'>HERE</a> to view with Product"


;

}
}

}

}
?>

right now I have it so that its at a ratio of height=3, and width=2...everything works fine but its not exactly what i want..

any ideas ?

I am using cakephp and i need a quick simple image upload and re-size script, can any one help?
