Anyhow. I'm spitting out a list of the Titles of my test table like so (and its working as expected): <?php $posting_sql = "SELECT * FROM postings"; $posting_results = (mysqli_query($cxn, $posting_sql)) or die("Was not able to grab the Postings!"); while($posting_row = mysqli_fetch_array($posting_results)) { echo "<li><a href='posting_details.php'>$posting_row[title]</a></li>"; } ?> Now as you can see: <a href='posting_details.php'> I am calling a new page, and that page contains this: <h2><?php echo "$posting_row[title]"; ?></h2> <p><?php echo "$posting_row[description]"; ?></p> It's no surprise it's not working (with many variations etc), but I am only familiar with using <form> GET or POST, and these of course are not form elements, so I cant seem to call them the same way. My suspicion (and from the research data I could find) is that I need to pass values in my link: <a href='posting_details.php'> ... I could not get it to work, but I was trying variations like: <a href='posting_details.php?get[title&get[description]]'> but it seems like I am screwing things up even more by doing this.. Anyhow. If anyone could show me a tutorial that covers this specifically or some suggestions on the best approach to this would be much appreciated.. Hi I'm trying to create a page where there is a grid of images and if you click on one of those images it will expand. Once the image has expanded and you click on the i icon that is below it, the i icon will display the information about that image. This isn't like a popup or anything like that, because when you click on the image and it expands, it expands in the same spot and it doesn't popup. Here is the html $str.='<div class="portfolio-banner-wrapper'.$langClass.'" style="position: relative;">'; $str.= '<a class="portfolio-arrow-left'.$langClass.' portfolio-navigate'.$langClass.'" href="javascript:void(0);"><img src="images/left-arrow.png" onmouseover="this.src=\'images/blue-left-arrow.png\'" onmouseout="this.src=\'images/left-arrow.png\'" /></a>'; $str.= '<a class="portfolio-arrow-right'.$langClass.' portfolio-navigate'.$langClass.'" href="javascript:void(0);"><img src="images/right-arrow.png" onmouseover="this.src=\'images/blue-right-arrow.png\'" onmouseout="this.src=\'images/right-arrow.png\'"/></a>'; $str.= '<div class="portfolio-banner-inner">'; $str.= $this->getPortfolioTest(); $str.= '</div>'; $str.='</div>'; $str.='<div class="overlay-bg'.$langClass.'">'; $str.= '<div class="additional-navigation-wrapper'.$langClass.'">'; $str.= '<div class="info'.$langClass.'" style="display: none;">'; $str.= '<a class="border-bottom-white padding-level-one inactive additional-nav-info1" href="javascript:void(0);">'; $str.= '<img class="icon" src="images/i_icon.png" />'; $str.= '<img class="nav-arrow no-action floatright" src="images/nav-arrow-white.png" />'; $str.= '<span class="clearboth"></span>'; $str.= '</a>'; $str.= '<div class="additional-nav-info-wrapper1">'; $str.= $this->i_icon(); $str.= '</div>'; $str.= '</div>'; $str.= '</div>';Here is the php

Please i need help on popup message when an image is clicked. Some one should help me with the code to place in my html document. Hi, I'm not super fluent in PHP or whatnot, but I currently have a website set up with an index.php to load the content pages within it. As part of the template, it consists of a header image, links, a photo, and a video. The content of each page loads within the specified area below the "template". Here's my question: My client wants to see a specific picture when they click one of hte links. For example, if they clicked on spot removal, the image beside the navigation should show spot removal and stay there on the index page while the content page, spot removal is shown. Does this make sense? I need help and fast. Screenshot included in attachment. And like I said, I'm not super fluent in PHP/MYSQL, so be very detailed when talking about what to do. I'd appreciate the help.

Can someone show me how to make it display only the images that exists in that folder ? What is the best/proper way to check if a supplied URL goes to an actual image? My site will allow users to enter an image URL (like "http://example.com/images/monkey.jpg"). I will store the URL they enter in a MySQL database and then will call it up later and do some resizing to these images. But I don't want to try to do any resizing if the URL they supply doesn't actually go to an image, or if it's blank (i.e. the user didn't enter a URL yet). So basically, I will run a MySql query to pull back the contents of the column called "imageurl". Let's say those contents are stored in a variable called $imageurl. This is what I'm trying to accomplish.... Code: [Select] if ($theimageurl does NOT contain a URL to an image OR is blank) { // do this } else { //run my resizing code } I guess i could do this to check to see if it's blank, but not sure this is proper/most efficient way to check that part of the issue... Code: [Select] if (trim($theimageurl) == "") But greater than the "is it blank" concern is that people may enter URLs that just to a regular website so whether it's at this point in my code (or for security, I should probably do it BEFORE inserting it into my database :/ ) so curious if there are any functions that check to see if it's an image URL or not. I know of file_exists, but I'm pretty sure that's just checking to see if a file exists and doesn't check image URLs. Any info/suggestions would be appreciated as always! And if there are any recommended functions to check/clean the user-entered URL BEFORE it's entered into the database, please share Thanks! Hello, i want to check whether image exist or not, but i can't get any data about it. I have tried everything: getimagesize, file_exist, filesize, etc. <? $info = @getimagesize('http://jargames.eu/ic.php?lf=files/All phone/240x320/007-quantum_of_solace_240x320.jar'); if(isset($info['mime'])){echo 'Image exist';} else{echo 'Image doesnt exist';} ?> Ty, for your help. Hi, I have an image handling php script which works fine here if the image is actually a readable format by the php program... Code: [Select] <?php //determine image type if($this->ext == 'jpeg' || $this->ext == 'jpg') { $imageObject = imagecreatefromjpeg($image); } elseif($this->ext == 'gif') { $imageObject = imagecreatefromgif($image); } ?> However, I tested the script with a random gif created in photoshop and i got an ugly php error returned saying the image was not the correct type for imagecreatefromgif even tho the image was a .gif file. In response I then tried to make a safety test, but it doesn't seem to work: Code: [Select] <?php //determine image type if($this->ext == 'jpeg' || $this->ext == 'jpg') { if(imagecreatefromjpeg($image)) { $imageObject = imagecreatefromjpeg($image); } else{ //now remove the old TEMP file ($image) unlink($image); return 'Sorry there is a file type error with the image you are uploading.';*/ } } elseif($this->ext == 'gif') { if(imagecreatefromjpeg($image)) { $imageObject = imagecreatefromgif($image); } else{ //now remove the old TEMP file ($image) unlink($image); return 'Sorry there is a file type error with the image you are uploading.';*/ } } ?> The $image can be either a jpg jpeg gif or png... Could anyone please tell me how to correctly check if the file is in readable by the php program in this context? Any help would be very much appreciated |
