PHP - Deletion Of Database Not Occuring
hi..i am creating an app for a school...registration is happening but deletion and updation is not
Similar TutorialsAre PHP sessions automatically destroyed after you close the browser, or they stay on server for ever, and are later accessible by id? (in case you do not destroy them before the browser exit). Thank you Hi, i have delete link for records and it goes to other page to delete all related records in tables. is there away to get confirmation before the delete process starts? <?Php include('session.php'); include('dbcon.php'); if(isset($_GET['Del'])) { $userid = $_GET['Del']; $query = "delete from staff where OracleID='".$userid."'"; $result = mysqli_query($con,$query); if($result) { echo "staff deleted"; } else { echo 'check the errors!'; } $query2 = "delete from attendance_records where OracleID='".$userid."'"; $result2 = mysqli_query($con,$query2); if($result2) { echo "records deleted"; } else { echo 'check the errors!'; } header("location:viewstaff.php"); } else { header("location:viewstaff.php"); } ?> how to add confirm message with php before deletion is processed? Hey, I've got an upload site where you can upload files and you get a direct link. I was wondering if it would be possible to offer a delete link too, where if you went to the link it would delete your file? Thanks. I'm building a site similiar to a web forum.
The code is all done, this is how it works:
CREATING POST:
------------------------
In PHP: Create Post -> Upload Images -> Remake Images (For security) -> Create Thumbnails (saved in uploads folder with unique name) With DATABASE: I have a table called "images" which tracks user uploaded images: uploaded_by_username (stores who posted it) image_status (tracking whether user aborted upload) thumbnail_confirm (tracking whether thumbnail generated successfully) post_association (tracking the post that the images go to) image_name (the image filename in uploads filefolder) time (unix time-stamp of upload tracking for admin purposes) DELETING POST: ------------------------ In PHP: Move all images into a "deleted_images" folder ( I'm afraid to use "unlink") With DATABASE: Delete all associated images from images table ( Is this risky? Should I use a second table and transfer the images? ) Anyhow, feedback appreciated in regards to how I designed this. Is this acceptable for the industry? I'm having a problem with a bit of code, which works for everything else, but just doesn't work when used for deletion of comments. The relevant code: Code: [Select] mysql_query("UPDATE $table SET LastEdited = '$time' WHERE PID = '$ID'", $Connection) or die(mysql_error()); header('Location: /'. $URL;This works, the resource is getting updated. What doesn't work is the revalidation after the redirect. The code I'm using for caching is: Code: [Select] header("Cache-Control: must-revalidate"); header("Last-Modified: ".gmdate("D, d M Y H:i:s", $Header['LTIME'])." GMT"); header("Etag: $etag"); header('Content-type: text/html; charset=UTF-8'); if ((@strtotime($_SERVER['HTTP_IF_MODIFIED_SINCE']) == $Header['LTIME']) && ( trim($_SERVER['HTTP_IF_NONE_MATCH']) == $etag)) { header("HTTP/1.1 304 Not Modified"); exit; } Its the exact same code used when posting comments on the site, aside from the query of cause. What i don't get, is why i have to hit update in my browser, to get it to re-validate. The $etag will only be updated if the sites source have been changed. I have a very tricky php problem here. At least for me. On a page that is editing a job entry. I have a database generated group of checkboxes some of which have been checked when the job was entered. So the script has to do two things generate the complete list of checkboxes and check the ones that have already been selected in the job request. The below script is what I've done trying to figure it out. Description of what I'm trying to do: I'm generating the the boxes with a call to my database for the list of checkboxes. Then I'm building an array with all the possible items that could be checked to compare against. Ok here is where I think my first problem is. I need to make a second query to another table "worklog" in the same database. This is where the list of checked items are stored. What is the best way to do this? A second query seems wrong "or at least not efficient" Code: [Select] <div class="text">Job Type (<a class="editlist" href="javascript:editlist('listedit.php?edit=typelist',700,400);">edit list</a>):</div> <div class="field"> <?PHP $connection=mysql_connect ("localhost", "user", "password") or die ("I cannot connect to the database."); $db=mysql_select_db ("database", $connection) or die (mysql_error()); $query = "SELECT type FROM typelist ORDER BY type ASC"; $sql_result = mysql_query($query, $connection) or die (mysql_error()); $i=1; echo '<table valign="top"><tr><td>'; while ($row = mysql_fetch_array($sql_result)) { $type = $row["type"]; if ($i > 1 && $i % 26 == 0) echo '</td><td>'; else if ($i) echo ''; ++$i; $aTypes = array ("Spec Ad Campaign", "100 x 100 Logo", "100 x 35 (Featured Developer/Broker)", "100 x 40 (Featured Lender)", "120 x 180 (Home Page Auto)", "120 x 45 (Half Tile - Jobs)", "120x60 (Section Sponsor)", "125 x 40 (Profile Page logo)", "135 x 31 (Autos)", "135 x 60 (Autos)", "135 x 60 (Logotile - Jobs)", "150 x 40 (Auto Logo)", "160 x 240 (monster tile)", "160 x 400 (Skyscraper)", "160 x 600 (Tower)", "170x30 (Section Sponsor)", "240 x 180 JPG/GIF Auto Video", "240 x 180 size FLV video ", "300 x 250 (Story Ad)", "300 x 600 (Halfpage)", "468 x 60 (Banner Jpg/Gif)", "728 x 90 (Leaderboard)", "95 x 75 (Sweeps Logo) ", "Agent Profile Page", "Contest", "Creative Change", "Employer Profile", "Holiday Shop", "Home of the Week", "HP Half Banner (234 x 60 Static)", "Mobile Ads (320x53 *300x50*216x36*168x28)", "Newsletter", "Peelback", "Pencil Ad", "Print", "Real Deals", "Resize ad campaign", "Roll-Over Skyscraper", "Site Sponsor logo (170x30)", "Splash Page Production", "Travel Deals Update", "Video Ad", "Web Development", "Web Maintenance", "Web Quote (or Design)"); $dbTypes = explode(',',$row['type']); foreach ($aTypes as $type){ if(in_array($aType,$dbTypes)){ echo "<input style='font-size:10px;' name='type[]' type='checkbox' value='$type' CHECKED><span style='color:#000;'>$type</span></input><br/>"; }else { echo "<input style='font-size:10px;' name='type[]' type='checkbox' value='$type'><span style='color:#000;'>$type</span></input><br/>"; } } } echo '</td></tr></table>'; ?> </div> after cloasing connection of database i still got the values form database.

What is most commonly used and or more reliable? Another topic i have trouble finding information on is actually positioning the output from you mysql database, is this practice done with tables?fields and rows? What is this method called? And is there more then one way to go about controlling result layout on your page? Sorry about the 1001 questions , but i am unable to find a clear answer on the topic ..especially question two . Thanks in advance. At the moment I am creating a search function for my website. The approach I have in mind is a pseudo-PHP database. To give an example: A HTML form will submit the results to a PHP file. HTML FORM - Colour: Black PHP RESULT PAGE - if ($_POST['color'] == 'Black') {readfile("./products/black/*.html");} HTML FORM - Price: <$50 PHP RESULT PAGE - if ($_POST['Price'] == '<$50') {readfile("./products/less50/*.html");} The problem here is if there is an item that is black and costs less than $50, then its going to be listed twice. There is probably some code I can write to ommit the listing of duplicate entries, but it is probably going to be messy, so I am wondering if its better to use a centralized MySQL database, rather than a pseudo-PHP database? I've never used MySQL and don't know much about it and this is my first real attempt at using PHP. I have a standard form that displays users current data from a mysql database once logged in(code obtained from the internet). Users can then edit their data then submit it to page called editform.php that does the update. All works well except that the page does not display the updated info. Users have to first logout and login again to see the updated info. even refreshing the page does not show the new info. Please tell me where the problem is as i am new to php.

I've got a My_SQL database containing articles, a summary for the article and a date.

But I must wonder, if doing this on a database would be faster. Would it be? I mean the example adobe shows I'm only using 19 pictures, but if I ever reach say 1000 pictures, would the php file be too big? Should I just make a database now or it doesn't matter? Also, the code above, which I took from a phpfreak member, has the pagination not working. Anyone care to do a diagnosis? Thanks! When I do this: $matches++; $sql_update_matches = mysql_query("UPDATE Live_Event SET matches='$matches' WHERE id='$show_id' AND promo_id='$promotion_id'"); But when it should update the database from 0 to 1, it update it to U. What is the problem? Hello everyone, I have put together a HTML form in which data is being collected, then verified with a PHP script before being posted into a SQL database. Is there anyway I can auto assign a unique ID to a database entry other than the default auto increment ID field? I want to be able to assign random ID numbers to tickets for an event and was hoping that something could be achieved in SQL..? Many thanks, BB2011 Hi there, *little heads up: English isn't my native language, so excuse me for any mistakes in spelling etc.* I've got a register/login script with activation mail, I secure my pages with this bit of code: Code: [Select] } if (!$HTTP_SESSION_VARS["ingelogd"]) { header("Location: login.php"); } Because if someone logs in, the session is made: Code: [Select] // bekijk of de gegevens juist zijn if (mysql_num_rows($res) >= 1) { // registreer sessie (of cookie) $ingelogd = mysql_result($res, 0); session_register(ingelogd); // setcookie("ingelogd", "$ingelogd", time() + 1 * 86400); echo "<p style=\"font-family: Arial, Helvetica, sans-serif; font-size: 13px; color: #000000;\"> U bent succesvol ingelogd.</p>"; echo "<p style=\"font-family: Arial, Helvetica, sans-serif; font-size: 13px; color: #000000;\"> Klik hier om <a href=\"home.php\">verder</a> te gaan.</p>"; } My question: When someone registered, they entered their 'real' name, which is then placed into the database in the same row as the username, password etc. I would like to state on the homepage which is secured 'Welcome 'Name'!'

Both tables will be populated with information that they give me at the same time (in other words from a single form). Just want to know, if I have a field called ID set to a primary key in both the tables, will that be enough to link them both together? Furthermore, what would the mySQL code look like if I wanted to view all the information referencing to specific ID? so info from the customer table and the other. Any and all help would be great.
