PHP - Image Properties
I am working on a header for a website and the code below pulls the file location for the image. I am wondering how (if possible) I could apply the repeat-x tag to the image. I know it can be done with html/css but I'm not sure how to go about it in PHP. Thanks in advance.
Code: [Select] <?php include 'db.php'; $result=mysql_query("SELECT location FROM header WHERE page='home'"); $row = mysql_fetch_row($result); echo "<img src=images/".$row[0] . "> "; ?> Similar TutorialsHi, I'm not 100% sure if this is HTML, PHP or Javascript, but my best guess is PHP. When you upload an image on Facebook, it automatically gathers the data about the image, i.e. size, device used (i.e. Canon, iPhone), title and description. It then outputs this on the page. Is there anyway to do this with PHP, instead of having to type all the information out again and upload that with the photo to a database? Cheers. __call is used when a method has been called, is there anything similar to __call but for properties? I wanted to use __get, but that is only for private properties... I'm doing some basic object coding to get my head around OOP PHP, but I've come across something I can't get to work. I've got two identical peices of code, MyClass is defined, MyClass2 is then defined as an extension of MyClass. MyClass has three properties Public, Private and Protected. In my first example I can access Public and Protected via a method in MyClass2, this class does NOT have a constructor. The second example has a constructor but I cannot access Public: Code: [Select] <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd"> <html> <body> <?php ECHO "MyClass2 does not have a constructor, Public & Protected both echo correctly from MyClass2->printHello!!!<BR>"; /** * Define MyClass */ class MyClass { public $public; protected $protected; private $private; protected $varXXX; function __construct() { $this->public = "Public"; $this->protected = "Protected"; $this->private = "Private"; //$this->printHello(); } function printHello() { echo $this->public . "!!!<BR>"; echo $this->protected . "!!!<BR>"; echo $this->private . "!!!<BR>"; } } /** * Define MyClass2 */ class MyClass2 extends MyClass { // We can redeclare the public and protected method, but not private protected $protected = 'Protected2'; /* function __construct() { echo $this->public . "#<BR>"; echo $this->protected . "#<BR><BR>"; //echo $this->private . "???<BR>"; } */ function printHello() { echo $this->public . "???<BR>"; echo $this->protected . "???<BR><BR>"; //echo $this->private . "???<BR>"; } } $obj = new MyClass(); //echo $obj->public . "<BR>"; // Works //echo $obj->protected; // Fatal Error //echo $obj->private; // Fatal Error //$obj->printHello(); // Shows Public, Protected and Private $obj2 = new MyClass2(); //echo $obj2->public; // Works //echo $obj2->private; // Undefined //echo $obj2->protected; // Fatal Error $obj2->printHello(); // Shows Public, Protected2, Undefined ?> </body> </html> RESULTS IN: Public??? Protected??? Code: [Select] <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd"> <html> <body> <?php ECHO "MyClass2 DOES have a constructor, Public does not work from MyClass2->printHello!!!<BR>"; /** * Define MyClass */ class MyClass { public $public; protected $protected; private $private; protected $varXXX; function __construct() { $this->public = "Public"; $this->protected = "Protected"; $this->private = "Private"; //$this->printHello(); } function printHello() { echo $this->public . "!!!<BR>"; echo $this->protected . "!!!<BR>"; echo $this->private . "!!!<BR>"; } } /** * Define MyClass2 */ class MyClass2 extends MyClass { // We can redeclare the public and protected method, but not private protected $protected = 'Protected2'; function __construct() { echo $this->public . "#<BR>"; echo $this->protected . "#<BR><BR>"; //echo $this->private . "???<BR>"; } function printHello() { echo $this->public . "???<BR>"; echo $this->protected . "???<BR><BR>"; //echo $this->private . "???<BR>"; } } $obj = new MyClass(); //echo $obj->public . "<BR>"; // Works //echo $obj->protected; // Fatal Error //echo $obj->private; // Fatal Error //$obj->printHello(); // Shows Public, Protected and Private $obj2 = new MyClass2(); //echo $obj2->public; // Works //echo $obj2->private; // Undefined //echo $obj2->protected; // Fatal Error $obj2->printHello(); // Shows Public, Protected2, Undefined ?> </body> </html> RESULTS IN: # << Missing the property's contents Protected2# ??? << Missing the property's contents Protected2??? Any ideas why I cannot access the property's contents in the second example when the only difference is that it has a constructor? I have a bunch of quasi-static values that must be available to the application. Most of them are set based on settings in a configuration file. Others are based on GET, COOKIE, or SESSION values, and utilize the database to get the actual values. The values will never be written to or modified by the application, only read.
It seems to me that I could create some sort of superclass which includes static methods and properties, and I could access any value by something like superclass::get('some.value'); I could design the class so that the values are queried from the DB or obtained from a parsed file only the first time they are requested, and for future requests, retrieved from a static property.
That being said, I have been told from more than one person that I am just doing it "wrong".
Please let me know what is wrong about it.
Thank you
I have wizard that asks several predefined questions to find-out user needs. at the end it must offer some items based on user answers. all of available items have some properties in common and one or two specific properties. what is the best way or algorithm to do this in JavaScript? e.g: Item 1 Properties: Name Weight Color Size Item 2 Properties: Name Size Weight Item 3 Properties: Name Color Size Thanks. Hello i just want to code a function for my editor that help me to do this: i copy a page with some note and picture in my editor,when i press send bottom editor find IMG tag in and upload it in my own server i can write a function for finding IMG tag and upload,but i don't know how i have to add automatic upload to my server,is there any body here can help me for coding this? or do you know one script or editor that have this properties on it? i use my sample editor I need to set a deep property if it is undefined or NULL such as shown below:
function setProperty($value, stdClass $config, $p1, $p2, $p3, $p4) {
if(!isset($config->$p1->$p2->$p3->$p4) || is_null($config->$p1->$p2->$p3->$p4)) {
$config->$p1->$p2->$p3->$p4=$value;
}
}
$config=json_decode(json_encode(['a'=>['b'=>['c'=>['x'=>null, 'y'=>123]], 'x'=>123],'x'=>['x'=>123], 'x'=>123]));
setProperty(321, $config, 'a','b','c','x');
setProperty(321, $config, 'a','b','c','y');
But I wish the function to work regardless of property depth and came up with the following. Recommendations for a cleaner way? Maybe I should be working with arrays and array_merge_recursive()?
function setProperty($value, stdClass $config, array $properties) {
$property=array_shift($properties);
if(!count($properties)){
if(!isset($config->$property) || is_null($config->$property)) {
$config->$property=$value;
}
}
else {
if(empty($config->$property) || !is_object($config->$property)) {
$config->$property=new \stdClass();
}
setProperty($value, $config->$property, $properties);
}
}
$config=json_decode(json_encode(['a'=>['b'=>['c'=>['x'=>null, 'y'=>123]], 'x'=>123],'x'=>['x'=>123], 'x'=>123]));
setProperty(321, $config, ['a','b','c','x']);
setProperty(321, $config, ['a','b','c','y']);
I implemented an endpoint which receives name/value pairs:
PUT someresource/123 {"name": "description", "value": "Some new description"}
I think I made a mistake, and should have implemented it as:
PUT someresource/123 {"description": "Some new description"}
The reason I think so is updating multiple properties is only (easily) possible using the later:
PUT someresource/123 {"description": "Some new description", "otherProperty": "bla bla bla"}
Assuming I am not using some 3rd party client library which only works with name/value pairs, any compelling reason why one shouldn't default to the later approach with key/values? Is this an effective way of accessing the $_GET and $_POST properties? I can see that the native $_GET function has been looped through so that $varName would be for example "username" and $value would be "Jeremy". Then they are both stored into an array called $getVars? Is this the best way of doing it, if not then why? foreach($_GET as $varName=>$value) $getVars[$varName]=trim(clean($value, 100)); foreach($_POST as $varName=>$value) $postVars[$varName]=trim(clean($value, 100));[/php] Kind regards, laanes This topic has been moved to Application Frameworks. http://www.phpfreaks.com/forums/index.php?topic=326397.0 Hi there, I am just wondering which way is the correct one if you want to create object properties/attribute dynamically at run time using magic method __set(), __get(), for example: class Foo{ public $data = array(); public function __set($name,$value){ $this->data[$name] = $value; } public function __get($name){ if ( isset($this->data[$name]) ){ return $this->data[$name]; } } } Or using the below way class Foo{ public function assign(array $data){ foreach($data as $key => $value){ $this->$key = $value; } } } I just encountered the second way in many places and I am totally confused . Is the __set() method called implicitly by the PHP engine in the second way or what? how come this is considered as a valid code ? your usual help is appreciated Hi Can you call Class A's methods or properties from Class B's methods? Thanks. After image is drop into container , I want to move copy of the original image to be move when original image dragend within container.

Edited by Biruntha, 08 January 2015 - 10:14 AM. 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 image
The 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 $name1. I don't want to have to manually update the 4 images. Here is the PHP: Code: [Select] <?php require_once('storescripts/connect.php'); mysql_select_db($database_phpimage,$phpimage); $uploadDir = 'upload/'; if(isset($_POST['upload'])) { foreach ($_FILES as $file) { $fileName = $file['name']; $tmpName = $file['tmp_name']; $fileSize = $file['size']; $fileType = $file['type']; if ($fileName != ""){ $filePath = $uploadDir; $fileName = str_replace(" ", "_", $fileName); //Split the name into the base name and extension $pathInfo = pathinfo($fileName); $fileName_base = $pathInfo['fileName']; $fileName_ext = $pathInfo['extension']; //now we re-assemble the file name, sticking the output of uniqid into it //and keep doing this in a loop until we generate a name that //does not already exist (most likely we will get that first try) do { $fileName = $fileName_base . uniqid() . '.' . $fileName_ext; } while (file_exists($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] != '') { $updateVals[] = 'name' . ($i + 1) . " = '{$values[$i]}'"; } } $updateNames = ''; if(count($updateVals)) { $updateNames = ", " . implode(', ', $updateVals); } $update = "INSERT INTO image (mid, cid, item, price, about, name1, name2, name3, name4) VALUES ('$mid', '$cat', '$item', '$price', '$about', '$values[0]', '$values[1]', '$values[2]', '$values[3]') ON DUPLICATE KEY UPDATE cid = '$cat', item = '$item', price = '$price', about = '$about' $updateNames"; $result = mysql_query($update) or die (mysql_error()); 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). Hello I am having problems uploading an image through a HTML form. I want the image to be uploaded to the server and the image name to be written to the mysql database. Below is the code I am using: Code: [Select] <?php if (isset($_POST['add'])){ echo "<br /> add value is true"; $name = $_POST['name']; $description = $_POST['description']; $price = $_POST['price']; $category_id = $_POST['category_name']; $image = $_FILES['image']['name']; //file path of the image upload $filepath = "../images/"; //mew name for the image upload $newimagename = $name; //new width for the image $newwidth = 100; //new height for the image $newheight = 100; include('../includes/image-upload.php'); mysql_query("INSERT INTO item (item_name, item_description, item_price, item_image) VALUES ('$name','$description','$price','$image')"); ?> Here is the image-upload.php file code: Code: [Select] <?php //assigns the file to the image $image =$_FILES["image"]["name"]; $uploadedfile =$_FILES["image"]["tmp_name"]; if ($image) { //retrieves the extension type from image upload $extension = getextension($image); //converts extension to lowercase $extension = strtolower($extension); //create image from uploaded file type if($extension=="jpg" || $extension=="jpeg") { $uploadedfile = $_FILES['image']['tmp_name']; $src = imagecreatefromjpeg($uploadedfile); }else if($extension=="png") { $uploadedfile = $_FILES['image']['tmp_name']; $src = imagecreatefrompng($uploadedfile); }else{ $src = imagecreatefromgif($uploadedfile); } //creates a list of the width and height of the image list($width,$height)=getimagesize($uploadedfile); //adds color to the image $tmp = imagecreatetruecolor($newwidth,$newheight); //create image imagecopyresampled($tmp,$src,0,0,0,0,$newwidth,$newheight,$width,$height); //set file name $filename = $filepath.$newimagename.".".$extension; $imagename = $newimagename.".".$extension; //uploads new file with name to the chosen directory imagejpeg($tmp,$filename,100); //empty variables imagedestroy($src); imagedestroy($tmp); } ?> Any help would be appreciated, fairly new to all this! Thanks!!! 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! This topic has been moved to mod_rewrite. http://www.phpfreaks.com/forums/index.php?topic=351137.0 |
