PHP - Image Display Script Won't Work
I came up with the following script for displaying an uploaded picture on a webpage but for some reason I can't pinpoint, the picture won't be displayed. I checked my database from php myadmin and sure enough, the picture was successfully uploaded but somehow, the picture won't be displayed. So here is the display script. I named it display_pic.php
Code: [Select] <?php //address error handling ini_set ('display_errors', 1); error_reporting (E_ALL & ~E_NOTICE); //authenticate user //Start session session_start(); //Connect to database require ('config.php'); //address error handling ini_set ('display_errors', 1); error_reporting (E_ALL & ~E_NOTICE); //include the config file require('config.php'); $image = stripslashes($_REQUEST[imname]); $rs = mysql_query("SELECT* FROM images WHERE member_id = '".$_SESSION['id']."' AND image_cartegory = 'main' "); $row = mysql_fetch_assoc($rs); $imagebytes = $row[image]; header("Content-type: image/jpeg"); print $imagebytes; ?> The tag on the html page that's supposed to display the picture reads something like this <img src="display_pic.php" width="140" height="140"> And just in case this might help, I will include the image upload script below, which I think worked just fine because my values were successfully inserted into the database. Code: [Select] <?php //This file inserts the main image into the images table. //address error handling ini_set ('display_errors', 1); error_reporting (E_ALL & ~E_NOTICE); //authenticate user //Start session session_start(); //Connect to database require ('config.php'); //Check whether the session variable id is present or not. If not, deny access. if(!isset($_SESSION['id']) || (trim($_SESSION['id']) == '')) { header("location: access_denied.php"); exit(); } else{ // Make sure the user actually // selected and uploaded a file if (isset($_FILES['image']) && $_FILES['image']['size'] > 0) { // Temporary file name stored on the server $tmpName = $_FILES['image']['tmp_name']; // Read the file $fp = fopen($tmpName, 'r'); $data = fread($fp, filesize($tmpName)); $data = addslashes($data); fclose($fp); // Create the query and insert // into our database. $query = "INSERT INTO images (member_id, image_cartegory, image_date, image) VALUES ('{$_SESSION['id']}', 'main', NOW(), '$data')"; $results = mysql_query($query); // Print results print "Thank you, your file has been uploaded."; } else { print "No image selected/uploaded"; } // Close our MySQL Link mysql_close(); } //End of if statmemnt. ?> So any insights as to why the script fails to display the image? Any help is appreciated. Similar TutorialsWell the subject line is pretty explicit. I found this script that uploads a picture onto a folder on the server called images, then inserts the the path of the image on the images folder onto a VACHAR field in a database table. Code: [Select] <?php //This file inserts the main image into the images table. //address error handling ini_set ('display_errors', 1); error_reporting (E_ALL & ~E_NOTICE); //authenticate user //Start session session_start(); //Connect to database require ('config.php'); //Check whether the session variable id is present or not. If not, deny access. if(!isset($_SESSION['id']) || (trim($_SESSION['id']) == '')) { header("location: access_denied.php"); exit(); } else{ // Check to see if the type of file uploaded is a valid image type function is_valid_type($file) { // This is an array that holds all the valid image MIME types $valid_types = array("image/jpg", "image/jpeg", "image/bmp", "image/gif"); if (in_array($file['type'], $valid_types)) return 1; return 0; } // Just a short function that prints out the contents of an array in a manner that's easy to read // I used this function during debugging but it serves no purpose at run time for this example function showContents($array) { echo "<pre>"; print_r($array); echo "</pre>"; } // Set some constants // This variable is the path to the image folder where all the images are going to be stored // Note that there is a trailing forward slash $TARGET_PATH = "images/"; // Get our POSTed variable $image = $_FILES['image']; // Sanitize our input $image['name'] = mysql_real_escape_string($image['name']); // Build our target path full string. This is where the file will be moved to // i.e. images/picture.jpg $TARGET_PATH .= $image['name']; // Make sure all the fields from the form have inputs if ( $image['name'] == "" ) { $_SESSION['error'] = "All fields are required"; header("Location: member.php"); exit; } // Check to make sure that our file is actually an image // You check the file type instead of the extension because the extension can easily be faked if (!is_valid_type($image)) { $_SESSION['error'] = "You must upload a jpeg, gif, or bmp"; header("Location: member.php"); exit; } // Here we check to see if a file with that name already exists // You could get past filename problems by appending a timestamp to the filename and then continuing if (file_exists($TARGET_PATH)) { $_SESSION['error'] = "A file with that name already exists"; header("Location: member.php"); exit; } // Lets attempt to move the file from its temporary directory to its new home if (move_uploaded_file($image['tmp_name'], $TARGET_PATH)) { // NOTE: This is where a lot of people make mistakes. // We are *not* putting the image into the database; we are putting a reference to the file's location on the server $sql = "insert into images (member_id, image_cartegory, image_date, image) values ('{$_SESSION['id']}', 'main', NOW(), '" . $image['name'] . "')"; $result = mysql_query($sql) or die ("Could not insert data into DB: " . mysql_error()); header("Location: images.php"); echo "File uploaded"; exit; } else { // A common cause of file moving failures is because of bad permissions on the directory attempting to be written to // Make sure you chmod the directory to be writeable $_SESSION['error'] = "Could not upload file. Check read/write persmissions on the directory"; header("Location: member.php"); exit; } } //End of if session variable id is not present. ?> The script seems to work fine because I managed to upload a picture which was successfully inserted into my images folder and into the database. Now the problem is, I can't figure out exactly how to write the script that displays the image on an html page. I used the following script which didn't work. Code: [Select] //authenticate user //Start session session_start(); //Connect to database require ('config.php'); $sql = mysql_query("SELECT* FROM images WHERE member_id = '".$_SESSION['id']."' AND image_cartegory = 'main' "); $row = mysql_fetch_assoc($sql); $imagebytes = $row['image']; header("Content-type: image/jpeg"); print $imagebytes; Seems to me like I need to alter some variables to match the variables used in the insert script, just can't figure out which. Can anyone help?? I had posted a similar post a few days back, about an display script which is supposed to retrieve a stored image from my database and displays it on an html page, but fails to do so. Someone suggested that I upload my image onto a folder on the server and then save the image path name in my database. I found this script(below) which does just that. It uploads the image into a folder on the server called images and stores the image path into a table in my database called images and I know this script works because i saw the file saved in the images folder and the path name inserted into the images table. Code: [Select] <?php //This file inserts the main image into the images table. //address error handling ini_set ('display_errors', 1); error_reporting (E_ALL & ~E_NOTICE); //authenticate user //Start session session_start(); //Connect to database require ('config.php'); //Check whether the session variable id is present or not. If not, deny access. if(!isset($_SESSION['id']) || (trim($_SESSION['id']) == '')) { header("location: access_denied.php"); exit(); } else{ // Check to see if the type of file uploaded is a valid image type function is_valid_type($file) { // This is an array that holds all the valid image MIME types $valid_types = array("image/jpg", "image/jpeg", "image/bmp", "image/gif"); if (in_array($file['type'], $valid_types)) return 1; return 0; } // Just a short function that prints out the contents of an array in a manner that's easy to read // I used this function during debugging but it serves no purpose at run time for this example function showContents($array) { echo "<pre>"; print_r($array); echo "</pre>"; } // Set some constants // This variable is the path to the image folder where all the images are going to be stored // Note that there is a trailing forward slash $TARGET_PATH = "images/"; // Get our POSTed variable $image = $_FILES['image']; // Sanitize our input $image['name'] = mysql_real_escape_string($image['name']); // Build our target path full string. This is where the file will be moved to // i.e. images/picture.jpg $TARGET_PATH .= $image['name']; // Make sure all the fields from the form have inputs if ( $image['name'] == "" ) { $_SESSION['error'] = "All fields are required"; header("Location: member.php"); exit; } // Check to make sure that our file is actually an image // You check the file type instead of the extension because the extension can easily be faked if (!is_valid_type($image)) { $_SESSION['error'] = "You must upload a jpeg, gif, or bmp"; header("Location: member.php"); exit; } // Here we check to see if a file with that name already exists // You could get past filename problems by appending a timestamp to the filename and then continuing if (file_exists($TARGET_PATH)) { $_SESSION['error'] = "A file with that name already exists"; header("Location: member.php"); exit; } // Lets attempt to move the file from its temporary directory to its new home if (move_uploaded_file($image['tmp_name'], $TARGET_PATH)) { // NOTE: This is where a lot of people make mistakes. // We are *not* putting the image into the database; we are putting a reference to the file's location on the server $sql = "insert into images (member_id, image_cartegory, image_date, image) values ('{$_SESSION['id']}', 'main', NOW(), '" . $image['name'] . "')"; $result = mysql_query($sql) or die ("Could not insert data into DB: " . mysql_error()); header("Location: images.php"); echo "File uploaded"; exit; } else { // A common cause of file moving failures is because of bad permissions on the directory attempting to be written to // Make sure you chmod the directory to be writeable $_SESSION['error'] = "Could not upload file. Check read/write persmissions on the directory"; header("Location: member.php"); exit; } } //End of if session variable id is not present. ?> Now the display image script accompanying this insert image script is shown below. Code: [Select] <?php // Get our database connector require("config.php"); ?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title>Dream in code tutorial - List of Images</title> </head> <body> <div> <?php // Grab the data from our people table $sql = "SELECT * from images WHERE image_cartegory = 'main'"; $result = mysql_query($sql) or die ("Could not access DB: " . mysql_error()); while ($row = mysql_fetch_assoc($result)) { echo "<div class=\"picture\">"; echo "<p>"; // Note that we are building our src string using the filename from the database echo "<img src=\"images/ " . $row['filename'] . " \" alt=\"\" />"; echo "</p>"; echo "</div>"; } ?> </div> </body> </html> Well, needless mentioning, the picture isn't displayed. Just a tiny jpeg icon is displayed at the top left hand corner of the page. Figuring out that the problem might be the lack of a header that declares the image type, I add this line header("Content-type: image/jpeg"); but all it does is display a blank white page, without the tiny icon this time. What am I missing? Any clues?? Hi, I am planning to display remote images with the following code but it seems to return errors. <?php $image_dir = 'http://www.domain.com/images/' ; $dir_handle = opendir( $image_dir ); $count = 0 ; $display = '' ; while( $filename = readdir($dir_handle)){ if( preg_match( '/$[a-z0-9]{4}_th\.jpg$/' , $filename ) ){ $display .= " <img src='$image_dir$filename' /> " ; $count++ ; if( $count % 10 == 0 ){ $count=0; $display .= "<br />"; } } } closedir( $dir_handle ); echo $display ; ?> I am thinking might be the $image_dir cannot use address format.... Errors is as follow Quote Warning: opendir(http://www.foo.com/images/) [function.opendir]: failed to open dir: not implemented in /home/jch02140/public_html/test.php on line 3 Warning: readdir(): supplied argument is not a valid Directory resource in /home/jch02140/public_html/test.php on line 6 Warning: closedir(): supplied argument is not a valid Directory resource in /home/jch02140/public_html/test.php on line 16 As the title says, on any mobile device, display: none; does not work. It will work when the CSS file is cached, however, when you refresh the URL (in any browser this will request a new version of the file) it appears that it will ignore display: none; calls. I tested this on several emulators.
I read somewhere that using both display: none; and visibility: hidden; worked, but I have not seen results for this.
Has anyone come across this before, or know a fix/work-around?

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!

I am using phpAdmin 2.6.0 and running Mysql 4.1.21. here is my situation.... I have a script that allows us to upload a new product name, product code, category and a PDF file to the data base. There is also a folder on the server that has the PDF files in it. I think I deleted the code on the page (library.php) that displays the files for the client to download. My goal here is after I upload everything I want it to then be displayed on the page with a link to the PDF file. Here is the page that has the links on it. I hope that I explained this correctly. I am not a programmer but do have some idea and have been reading up on php to try and figure this out. I am looking to create the script that would display the links on the library.php page. Any help would be great. The other link is to the script that allows us to upload. www.pennstateind.com/library.php www.pennstateind.com/lib-admin.php Hi there, I am starting to learn OO PHP programming. After running math.php, it gives an output 'Use only numbers'. Why? I don't understand this. math.php <?php require('MathClass.php'); $c = new MathClass(); echo $c->add(5,10,15,20); ?> MathClass.php <?php class MathClass{ function add(){ $args = func_num_args(); $sum = 0; $i = 0; for ($i ; $i < $args ; $i++){ is_int(func_get_args($i)) ? $sum += func_get_args($i) : die('Use only numbers'); } return $sum; } } ?> Server version: 5.1.53-log I have the following queries Code: [Select] SELECT user_id FROM phpbb_profile_fields_data WHERE pf_rsname = "Atroxide" LIMIT 1 SELECT user_id FROM phpbb_profile_fields_data WHERE pf_rsname = "Delia Smith" LIMIT 1 SELECT user_id FROM phpbb_profile_fields_data WHERE pf_rsname = "espinozagabe" LIMIT 1 SELECT user_id FROM phpbb_profile_fields_data WHERE pf_rsname = "Jaunty1" LIMIT 1 SELECT user_id FROM phpbb_profile_fields_data WHERE pf_rsname = "lvoos" LIMIT 1 All 5 of these queries are executed at a different time (in a foreach loop). All 5 except for the one below returned a result. Code: [Select] SELECT user_id FROM phpbb_profile_fields_data WHERE pf_rsname = "Delia Smith" LIMIT 1 I couldn't figure out why it wasn't working so I copy pasted it into PHPMyAdmin and it returned the result I was looking for. What could cause for PHPMyAdmin to work but not the exact same query in a php script to not? It didn't return an error using mysql_error() either. Pretty sure its irreverent but here is the php script. Code: [Select] foreach ($online as $username => $activity) { $query = " SELECT user_id FROM phpbb_profile_fields_data WHERE pf_rsname = \"" . $username . "\" LIMIT 1 "; $result = $db->query($query); } The table is Code: [Select] user_id mediumint(8) UNSIGNED No 0 pf_rsname varchar(255) utf8_bin Yes NULL Hello !
How I can make a script of my PHP code to work even if my website is not running
Can I make this with php ?
Hello all, I have followed the stop on this page to what I thought was a tee: http://www.inkplant.com/code/pull-tw...-your-site.php but I guess I was wrong because I am getting errors. I have setup the database and table properly and created all files, but when I do step 4 and place the code on my site I am getting this error Code: [Select] Fatal error: Call to undefined function dbQuery() The api pull went fine and it stored the tweets in the database, but it can't display them. Is there a missing step about connecting to the database somewhere? Thanks for any help Hello I have an array that I would like to display as a family tree... and am looking for an example script that will allow me to do this.

So, if I want 5 generations I want to generate a tree with 63 elements or boxes Any help would be appreciated Thanks Code: [Select] <?php ob_start(); session_start(); require_once ("functions.php"); $returnurl = urlencode(isset($_GET["returnurl"])?$_GET["returnurl"]:""); if($returnurl == "") $returnurl = urlencode(isset($_POST["returnurl"])?$_POST["returnurl"]:""); $do = isset($_GET["do"])?$_GET["do"]:""; $do = strtolower($do); switch($do) { case "": if (checkLoggedin()) {include("usernav.php");?> <h3>User Logged In</h3> <p>This is the members only area.</p> <?php } else {?> <a name="User Panel"></a> <h1>User Panel</h1> <h3>User Login</h3> <form name="login" action="login.php?do=login" method="POST" onsubmit="return aValidator();"> <input type="hidden" name="returnurl" value="<?$returnurl?>"> <table cellPadding=3 width=225 border=1> <tr> <td colSpan=2> <center> <p><b>Members-Only Area!</b></font></p> </center></td></tr> <tr> <td align=center width=70>Username:</td> <td><input type="text" name="username"></td></tr> <tr> <td align=center width=70>Password:</td> <td><input type="password" name="password"></font></td></tr> <tr> <td align=middle colspan=2> <input type="submit" name="submit" value="Login"></td></tr> <td align=middle colSpan=2> <input type="checkbox" name="remme" value="on"> Remember me for the next time I visit</td> </form></table></td> <?php } break; case "login": $username = isset($_POST["username"])?$_POST["username"]:""; $password = isset($_POST["password"])?$_POST["password"]:""; if ($username=="" or $password=="" ) { echo "<h1>Username or password is blank</h1>";//this does not show when the input(s) are blank clearsessionscookies(); header("location: index.php?returnurl=$returnurl"); } else { if(confirmuser($username,$password)) { createsessions($username,$password); if ($returnurl<>"") header("location: $returnurl"); else { header("Location: index.php"); } } else { echo "<h1>Invalid Username and/Or password</h1>";//this message does not show when the user login invalid clearsessionscookies(); header("location: index.php?returnurl=$returnurl"); } } break; case "logout": clearsessionscookies(); header("location: index.php"); break; } ?> What maybe the case, could anyone help me with this? Thanks Ted. Hello, The following is my situation where I seem to get a 500 error code from the linux server: i have an 'index' file like this: Code: [Select] <?php require("includes/config.php"); $a = $_REQUEST['a']; switch ($a) { case "home": include("frontpage/main.php"); case "user-process": include("user-process.php"); } ?> config.php is something like this: Code: [Select] <?php require(includes/classes/session.class.php); require(includes/classes/user.class.php); require(includes/classes/db.class.php); ... ?> Now if we fall into the case "home" it works fine. Instead, if we fall into user-process it writes to the logs file Fatal Error: Class User does not exist bla bla bla. Why doesn't it exist ? every class is included in the config.php file then index.php includes first config.php ( which has all the classes) and then includes the requested page. I also have a .htaccess file which is as follows: Code: [Select] RewriteEngine On RewriteRule ^([^/\.]+)?/?([^/\.]+)?/?([^/\.]+)?/?([^/\.]+)?/?([^/\.]+)?/?([^/\.]+)?/?([^/\.]+)?$ index.php?a=$1&b=$2&c=$3&d=$4&e=$5&f=$6&g=$7 [NC,L] which is used to access in a SEO friendly way the pages that users request. This is my script I want to display but it does not show in the page just blank. <td><object width="220" height="148"><param name="movie" value="http://www.youtube.com/user/THEWORLDOFTRAVEL#p/search/2/uX9nd3xM_MY=1&h1=enUS&color1=0x234900&color3=34900&"></param><param name="allowFullScreen" value="true"></param><param name="allowscriptaccess" value="always"></param><embed src="http://www.youtube.com/user/THEWORLDOFTRAVEL#p/search/2/uX9nd3xM_MY=1&h1=enUS&color1=0x234900&color3=34900&" type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" width="220" height="148"></embed></object></td> This topic has been moved to Other Programming Languages. http://www.phpfreaks.com/forums/index.php?topic=312147.0 |
