PHP - Passing An Variable From One Php File To Another
Hi Guys,
I'm working on an image resizer, to create thumbnails for my page. The resizer works on principle of include a DIRECT link to the image. But what I want to do is put in the PHP Variable in the URL string, so that it points to that file and resizes it accordingly. My code is as follows : Code: [Select] <img src="thumbnail.php?image=<?php echo $row_select_property['image_url']; ?> Image Resize : Code: [Select] <?php // Resize Image To A Thumbnail // The file you are resizing $image = '$_GET[image_url]'; //This will set our output to 45% of the original size $size = 0.45; // This sets it to a .jpg, but you can change this to png or gif header('Content-type: image/jpeg'); // Setting the resize parameters list($width, $height) = getimagesize($image); $modwidth = $width * $size; $modheight = $height * $size; // Creating the Canvas $tn= imagecreatetruecolor($modwidth, $modheight); $source = imagecreatefromjpeg($image); // Resizing our image to fit the canvas imagecopyresized($tn, $source, 0, 0, 0, 0, $modwidth, $modheight, $width, $height); // Outputs a jpg image, you could change this to gif or png if needed imagejpeg($tn); ?> What I am trying to do is pass on the variable "image=<?php echo $row_select_property['image_url']; ?>" to the Thumbnail script. At the moment I am passing it through the URL string, but it doesnt seem to load the graphic. I'll try expand on this more, should you have questions as I am finding it a little difficult to explain. Thanks in advance. Similar TutorialsHi, I need to pass value of variable to another php file. I thought it is possible to do it as following: <form action="products.php"> <INPUT TYPE=hidden NAME='id' . VALUE='$id'> </form> But the problem is like that. The php file inside which I want to write above html code has not using <form> tag and it has no buttons. So how to initiate the transfer of variable into another php file? Is the above idea is not the good idea? Are there any another ways? Hi all, I have my whole script working only the name of the upload file won't pass to the process.php page. Any help much appreciated.

After a long bout of trouble-shooting, I found out that it has something to do with mod_security that they have suddenly enabled (have no idea as I'm not a Linux guy). They told me they fixed the problem on my domain by whitelisting it as an exception, but strangely, even though the permissions error went away, the actual src= box of the iframe, which was the url variable I was passing in the url, no longer loads. So.. I'm trying to break this down into the simplest form to figure it out. I just understand php basics so needing some verification that I'm doing this right/wrong. Here's my code.. page1.php Code: [Select] <? $testurl = "http://google.com"; ?> <a href="http://mysite.blah/page2.php?url=<? echo $testurl; ?>">page2.php</a> page2.php Code: [Select] if (isset($_GET['testurl'])) echo $testurl; else echo "sorry dude"; I am only able to print "sorry dude". Am I doing something wrong or shouldn't this send the url? Thanks for the help! hello all, I'm new here and I'm learning mysql/php. Currently I have a dynamic table on one of my webpages, and the loop code looks like this:while ($i < $numRows) { $fname = mysql_result($result, $i, "fname"); $fcode = mysql_result($result, $i, "fcode"); $ftype = mysql_result($result, $i, "ftype"); $fdesc = mysql_result($result, $i, "fdesc"); ?> <tr> <td><a href="showfunction.php?fname=<?php echo "$fname"; ?>" target="_self"> <?php echo "$fname"; ?></a></td> <td> <?php echo "$fdesc"; ?> </td> <td><div align="center"> <?php echo "$ftype"; ?> </div></td> </tr> <?php $i++; } ?> what I would like to do is pass the ''fname'' variable to the "showfunction" page so it can printed from the database. Here is the relevant portion of the page:<body><div class="codeblock"> <div class="title">Code:<br /> </div><code><pre> <?php echo $fcode; ?> </pre></code></div> <br /><pre><hr /> </pre> I know that doesn't work, and I didn't expect it to because there is no way to 'get' the 'fname' variable from the preceeding script. I do not want to use the GET method with this because from what I understand, you can only use it with Forms. I really don't want to put controls in all of my table fields just to be able to pass the function name to the next page. Does that make sense? If I could get a jumpstart on this one last hurdle, I would appreciate it. thank you so much! Cheers. How, if possible, can a $var be passed to the forms action php file?

Thanks Trying to set up an error message when someone tries to upload a file without the approved .ext. I have it working so it won't up load but I am trying to get an error to print out. I was thinking that I could do something like this if the ext are wrong set $errorMsg1 == 1; and then the page will refresh and I would pass that variable to echo out if ($errorMsg1 == 1){ echo "Invalid"; } else { but it isn't passing can anyone help me with this? Tyring to keep it simple this is the code to select an image else{ $result = mysql_query("SELECT * FROM photos WHERE userID LIKE '$clientID'"); while ($r=mysql_fetch_array($result)) { $photo_1=$r['photo_1']; $photo_2=$r['photo_2']; $photo_3=$r['photo_3']; $photo_4=$r['photo_4']; $photo_5=$r['photo_5']; echo " <form enctype='multipart/form-data' action='' method='POST'> <input type='hidden' name='MAX_FILE_SIZE' value='500000' /> <div id='imageTop'>Image &#35;1</div> "; if ($errorMsg1 == 1){ echo "Invalid"; } echo " <div id='imageBottom'> <span class='image'>"; if (empty($photo_1)) { echo " <img src='uploads/noPhoto.gif' width='75' height='75' class='zip'> "; } else { echo "<a href='uploads/$photo_1' ><img src='uploads/$photo_1' width='75' height='75' class='zip'></a> "; } echo " </span> <span class='action'> <input type='file' name='photo_1' class='zip'><br><br> <input type='checkbox' name='delete_1'>Select to Delete image </span> </div> } this is the code of what to do with that image if (isset($_POST['delete_1'])) { $query = "UPDATE photos SET photo_1='' WHERE userID='$clientID'"; $result = mysql_query($query) or die(mysql_error()); echo " <div id='aboutUpdate'><img src='img/loader.gif'> Information is updating</div> "; echo "<meta http-equiv=refresh content=\"0; URL=photos.php\">"; } else if ($one != NULL) { $extension = strrchr($_FILES['photo_1']['name'],'.'); $extension = strtolower($extension); if($extension != '.jpg' && $extension != '.gif' && $extension != '.png' && $extension != '.bmp' ){ $errorMsg1 == 1; echo "<meta http-equiv=refresh content=\"0; URL=photos.php\">"; } else { $photoNumber="_1"; $finalName="$clientID$photoNumber"; $save_path = "uploads/"; $target_path = $save_path . basename( $_FILES['photo_1']['name']); $NewPhotoName = $finalName; $withExt = $NewPhotoName . $extension; $filename = $save_path . $NewPhotoName . $extension; if(move_uploaded_file($_FILES['photo_1']['tmp_name'], $filename)) { $query = "UPDATE photos SET photo_1='$withExt' WHERE userID='$clientID'"; $result = mysql_query($query) or die(mysql_error()); echo " <div id='aboutUpdate'><img src='img/loader.gif'> Information is updating</div> "; echo "<meta http-equiv=refresh content=\"0; URL=photos.php\">"; } } else { This is driving me MAD!

I have a page with a javascript game where the player moves around on a map. They have an X and Y coordinate, but I'm having a problem. The problem is I need to store that info in a database, and I'm having trouble learning AJAX. Heres a little list of things: Play loads the game. A php variable is taken from a database. The player goes to those X and Y coordinates. The player may move around. Once they move, the player is sent to a php page that updates the Database information. The page is refreshed to the game again, where they may then move around some more. The problem is, when the page is changed the values are lost. For some reasons cookies aren't working at all (like just not working for anything, even a completely different file.) I heard something about using $_GET or $_POST, but I dont see how... I'm new to php and was wondering how I would be able to do the following: -I have a search page that allows someone to search for a particular user in the database -In the results, I want to have a <a href> link to another page which will run a sql query based on which user's link was clicked and list their posts. So right now I have been trying this code to build that href link: Code: [Select] echo '<td><a href="viewuser.php?username='.urlencode($row['username']).'>View user</a></td>'; However on the following page it is unable to retrieve the 'username' field. Please forgive my limited knowledge of php. I am trying to pass a variable from 1 page to the next. I have SCRIPT A (I didn't write it) that parses an rss feed and then calls SCRIPT B to insert it into a database. Everything works great.. and all I'm trying to do is add a new piece of information. In my db, I added a column called 'city'. There are currently 25 different SCRIPT A's (25 different city names). I could create 25 SCRIPT Bs and call them individually, but I'm trying to use 1 SCRIPT B and just send the city name. I've read about POST and GET but still not sure on this? Can't I just hard code my city name into each SCRIPT A like this: Code: [Select] $city = "miami"; And then put this at the top of SCRIPT B? Code: [Select] $city = $_GET['city']; Well.. apparently, I can't because that doesn't work. Again.. sorry for the dumb question. It's my first time attempting anything with php. Thanks.
