PHP - Resize Textarea To Fit Html Td

I have a form that generates html code, and displays it in a textarea with submit button.

I want to submit button to take the data entered in that textarea1 on page 1, and upload to textarea2 on page 2
How can I do this? I have no idea where to start.

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

Hi,

I'm having to look hard for the right way to do this.

Basically the image is sent to the database, and is called to be put in a table, but the images are all different sizes, i would like them all one size, whats the best way to do this with my existing script:

Code: [Select]
<?php 
 error_reporting(E_ALL);
 ini_set("display_errors", 1);
 echo '<pre>' . print_r($_FILES, true) . '</pre>';

 
 //This is the directory where images will be saved 
 $target = "/home/users/web/b109/ipg.removalspacecom/images/COMPANIES"; 
 $target = $target . basename( $_FILES['upload']['name']); 
 
 //This gets all the other information from the form 
 $company_name=$_POST['company_name']; 
 $basicpackage_description=$_POST['basicpackage_description']; 
 $location=$_POST['location']; 
 $postcode=$_POST['postcode'];
 $upload=($_FILES['upload']['name']); 
 
 // Connects to your Database 
 mysql_connect("***", "***", "***") or die(mysql_error()) ; 
 mysql_select_db("***") or die(mysql_error()) ; 
 
 //Writes the information to the database 
 mysql_query("INSERT INTO `Companies` (company_name, basicpackage_description, location, postcode,  upload) VALUES ('$company_name', '$basicpackage_description', '$location', '$postcode',  '$upload')") ; 
 echo mysql_error();
 
 //Writes the photo to the server 
 if(move_uploaded_file($_FILES['upload']['tmp_name'], $target)) 
 { 
 
 //Tells you if its all ok 
 echo "The file ". basename( $_FILES['upload']['name']). " has been uploaded, and your information has been added to the directory"; 
 } 
 else { 
 
 //Gives and error if its not 
 echo "Sorry, there was a problem uploading your file.";

hello
I want download a file from another website and resize it to new size then reduce quality to 60% and save in on my host.
this is my code about download and reduce quality.
//images address
$images1 = textbetween('<a href="','"',$text0);
//save images
$im = imagecreatefromjpeg($images1); // original image
//reduce image quality
imagejpeg($im, "/public_html/static/images/book/".$imagename.".jpg" , 60); // save to new image, third value is quality (0-100) if not specified its the default (75)
can anyone help me to resize it?


thank you

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.

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?

The below code inserts image details to db and uploads pic to folder, can anyone show me how to resize it aswell. please

Hello,

How could I resize the image to 320x480 before it is uploaded. Here is the code for the upload:
Code: [Select]
<?php
require("connect.php");

$query = mysql_query("SELECT * FROM items ORDER BY id DESC");
if (mysql_num_rows($query) > 0) {
  $row = mysql_fetch_assoc($query);
  $id = $row['id'];
  $id++;
echo $id."<br>";


$username = $_GET['user'];
$dateofupload =  date("Y-m-d");
$uploaddir = './pqimages/'.$dateofupload.'/';
$file = basename($_FILES['userfile']['name']);
$uploadfile = $uploaddir.$id.".jpg";



if (move_uploaded_file($_FILES['userfile']['tmp_name'],$uploadfile)){

echo "http://randomaydesigns.com/pqimages/{$file}";
$userid = mysql_query("SELECT * FROM users WHERE username ='$username'");
while ($row2 = mysql_fetch_assoc($userid)){

$userid = $row2['id'];


$updateuserlastupload = mysql_query("UPDATE users SET lastupload='pqimages/".$dateofupload."/$id.jpg' WHERE username='$username'");

$updateuser = mysql_query("INSERT INTO items VALUES('','$userid','1','i','','','pqimages/".$dateofupload."/$id.jpg','0','a','$dateofupload')");
}
}


}

?>Cheers,

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.

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.

I am trying to replace image code and resize it at the same time
but gave me error.
