PHP - [php] Manipulate An Image With Gd
Hello all !
My question is: I've got an image: http://extreme-redeemer.com/math_captcha/image.php I want to "decrypt" it, to get 3 different parts. The first number, the operatror and the last number. I actually want to be able to make this operation in PHP. I know PHP well, but I'm not familiar with the GD library! Thank you so much! Similar TutorialsI need to be able to pull this URL in my form action: /login?onlogin=http://domain.com/messaging?action=read&cid=130&utm_source=new_message&utm_medium=email&utm_campaign=direct_mesage_link I need everything after "/login?onlogin=" but when I do: Code: [Select] if (isset($_GET['onlogin'])) { echo $_GET['onlogin']; die(); } It only returns http://domain.com/messaging?action=read and I need it to return the entire URL. How can I achieve this? I have an array and I would like to insert commas and the word 'and' to make a sentence using an array. For example... $sports = array(baseball, soccer, tennis); Ted played baseball, soccer and tennis or Ted played baseball, soccer, boxing and tennis What's the best way to do this? In the past, whenever I write an image upload script in php that needs to generate a thumbnail or resized version, I have had to make sure the image is a reasonable size before uploading otherwise you get the old 'allowed memory bytes exceeded' thing. What are my options if I want people to be able to upload a full size image from their camera i.e. a 15-20mb 4000x3000px image and then have a thumbnail and something like 500px wide version for displaying on the site? The large unaltered original needs to be stored as well as it will be used for prints. Is this just not possible with PHP? Or is it down to needing a dedicated server? Howdy - good evening dear PHP-Friends, i am new to programming. I have a couple of (hundred) adress( and data ) lines that look like the following: {'url': 'http://Url.org/~dilbert/', 'cname': 'dibert_1', 'name': 'Dilbert_1', 'email': 'dilbert_1@ncf.ca'} {'url': 'http://Url.org/~dilbertwo/', 'cname': 'dilbert_2', 'name': 'Dilbert_2', 'email': 'dilbert_2@hotmail.com'} {'url': 'http://Url.org/~dilberthree/', 'cname': 'dilbert_3', 'name': ' Dilbert_3', 'email': 'dilbert_3@gmail.com'} and so forth.... Well - i want to put the data into the Thnderbird-Adressbook: But the adressbook does not take the data in this format. So what can i do with the data-set. How to Manipulate!? Note: At least a name and a E-Mail-Adress is needed. Nothing more - but - a Mail - Adress is pretty important. i look forward to hear from you if you have any further questions - jus t lemme know! Hi Are there any libraries /api that allow you to upload vector files such as: AI file, TIFF or EPS and Manipulate using PHP. Operations such as changing colors, measurements etc. Any help is appreciated! I have an existing PHP array ($products) with various fields in it.... id / title / description / link / image link etc. etc. as per requirements for a Google Products feed (https://support.google.com/merchants/answer/7052112). My issue is that, for clothing, Google want a separate record for each size available. My array includes the "size" field as a comma separated list e.g. 6,8,10,12,14 or XS,S,M,L,XL etc. etc. So before creating the feed (a text file, which is currently outputting fine except for the size field issue) I need to duplicate each id where there's more than 1 size in that field, for each size, and then manipulate the fields a little so that (ignoring all the duplicated fields that would remain unchanged) instead of the single record : -
id size item group id I'd have 11 records, item group id would be what the id is, the size appended to the id, and the size field only one (in sequence of those from the original), so: - id size item group id
52-6 6 52 That's just one product....there are quite a lot, each with multiple sizes, but all in the same format within the $products array. As always, any help / pointers / solutions much appreciated! Hi, I've read a lot of places that it's not recommended to store binary files in my db. So instead I'm supposed to upload the image to a directory, and store the link to that directory in database. First, how would I make a form that uploads the picture to the directory (And what kinda directories are we talking?). Secondly, how would I retrieve that link? And I guess I should rename the picture.. I'd appreciate any help, or a good tutorial (Haven't found any myself). The script for creating a new file name for the image:
$validextensions = array("jpeg", "jpg", "png"); //Extensions which are allowed $ext = explode('.', basename($_FILES['file']['name'][$i]));//explode file name from dot(.) $file_extension = end($ext); //store extensions in the variable $new_image_name = md5(uniqid()) . "." . $ext[count($ext) - 1]; $target_path = $target_path . $new_image_name;//set the target path with a new name of imageThe script creates a new file like: f6c9b8d9db05366c3504210cded9ddb2.jpgand moves the file to the "uploads" folder. And then the script also creates a thumbnail with the same file name and moves the file to the "thumbs" folder. The issue I am having is that the same ID code could happen again for a different image in the database, thus I would be calling a different original sized image than the thumbnail image. My question is: How to avoid this issue of the same ID code has happened again for a different file. What is the proper way to reference the anchor tag of the thumbnail image to its actual original sized image? With the script I have the thumbnail image would be coming from the "thumbs" folder and the anchor tag would get referenced to the "uploads" folder to get the original sized image. Edited by glassfish, 12 October 2014 - 05:51 AM. How can i edit just one image at on time with a multiple image upload form? I have the images being stored in a folder and the path being stored in MySQL. I also have the files being uploaded with a unique id. My issue is that I want to be able to pass the values of what is already in $name2 $name3 $name4 if I only want to edit $name1. I don't want to have to manually update the 4 images.

'.' . $fileName_ext; } while (file_exists($filePath.$fileName)); $file_names [] = $fileName; $result = move_uploaded_file($tmpName, $filePath.$fileName); } if(!get_magic_quotes_gpc()) { $fileName = addslashes($fileName); $filePath = addslashes($filePath); } $fileinsert[] = $filePath; } } $mid = mysql_real_escape_string(trim($_POST['mid'])); $cat = mysql_real_escape_string(trim($_POST['cat'])); $item = mysql_real_escape_string(trim($_POST['item'])); $price = mysql_real_escape_string(trim($_POST['price'])); $about = mysql_real_escape_string(trim($_POST['about'])); $fields = array(); $values = array(); $updateVals = array(); for($i = 0; $i < 4; $i++) { $values[$i] = isset($file_names[$i]) ? mysql_real_escape_string($file_names[$i]) : ''; if($values[$i] != '') { $updateVals[] = 'name' .

Can I get some help or a point in the right direction.
I am trying to create a form that allows me to add, edit and delete records from a database.
I can add, edit and delete if I dont include the image upload code.
If I include the upload code I cant edit records without having to upload the the same image to make the record save to the database.
So I can tell I have got the code processing in the wrong way, thing is I cant seem to see or grasp the flow of this, to make the corrections I need it work.
Any help would be great!

Thanks!!! Hello, I've had success creating a cool vanity QR code with rounded edges for my organization by generating a standard QR code, then applying a noise -> median effect in Photoshop to get the edges rounded among some other effects. Photoshop is great, but I want to automate this. I found a great PHP library to generate QR codes. The part I don't get is the rounding of the hard edges. I've seen other sites do it like this one. So far google searches are yielding rounded corner tutorials. Any thoughts on how to do this with GD or ImageMagic? Best regards, Chris Hello, Five images will be displayed inside a division. There will be a previous and next button/link. If someone click the next button the next image will be added in that div and the first image will be gone from that div. The previous button/link will do the same thing. Is it possible with php? I am confused if it's a javascript or ajax question. Thanks. Would like to be able to click on a radio button that represents an image. Once selected and submitted, have that image display on another page. I have an idea, but need some guidance. BTW, is using php only doable? Is there a simpler or more elegant way to do this? Thanks all!

However, not all image are square, so when they are resized, they lose their ration and look squashed. Is there a way I can display just a part of the original image, say 40px x 40px on the top middle of each image? I hope that makes sense |
