PHP - Please Help Me Resize My Images

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.

I am looking for a script that can change the width and height of an image when it is uploaded to our web site through a web form. Any help would be great.

When i use the following script to upload and resize an image, it throws out errors (see after script)

        print "<p>Please upload only an image with the extension .jpg or .jpeg or .gif ONLY<br><br>";

I want to resize an image to fit within a rectangle.

Lets say my rectangle is 400 wide and 200 tall.

My image is 300x300.

It should take, and make the rectangle 200 tall, then scale the width accordingly.

I wrote a function a while back that resizes inside a square, but that was a little easier, since you know to constrain by height if height is greater than width, and to constrain by width if width is greater than height.

$w = $stats[0];

$h = $stats[1];

if($dim){ // constrain image

if($w > $h){

$h = ($h / $w) * $dim;

$w = $dim;

} else {

$w = ($w / $h) * $dim;

$h = $dim;

}

}


Thats my code to constrain inside a box. It gets the starting h and w from $stats, which is loaded from getimagesize. Then it sets a new h and w based on dim, which is the size of the box.

The new version will need dimW and dimH, instead of just dim.

Can anyone help me out?

I want to set the size to 100 x 100, which part of the code that I need to edit?

Hello,

I use this code to resize images:

  $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 ($t == 'image/png'){@imagepng($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']);

    $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

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?

Thanks in advance..sorry for my english please 

Hi!

I'm looking for a script that can do the following:

upload one or preferably fx. five image files(jpg)

resizes them to a specific size if they exceeds that size.

create a thumbnail

No files above 100kb can be uploaded.

uploaded and/or processed files must be renamed with a unique file name.

Work with php5


I have searched the internet for a script like that, but I can't find one that matches my needs. Also, the code must include good comments and nott be to hard to understand. So as basic code as possible.

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?

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.

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());

$image_name = addslashes($_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;

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 ?

Hi Guys,

I have this script below which inserts the file name and path into my datebase and uploads the file into the customers folders (which is creates dynamically).

The is no error checking as I want it to be as flexible as possible but mostly(99.999%) the files I upload are JPEG and PDF's.

I would like my script to be able to resize the files above automatically to be smaller.

Please is this possible thanks!

Here is script:

Hello, i have a textarea which can contains too long sentences in a row and many new lines

i have a div which is auto height and retrieve each message from the textarea .. the thing is that i want to resize it so it can fit inside the width of the dive which is about 700px .. i tried getting all sentences between each newline and resize then if they are >80 chars and then add <br />

but the login doesnt seem correct..

how else can i achieve that?

thanks.
