PHP - Sql Delete From Row By Clicking A Button
Im displaying the results of a database by using a while loop... so Im trying to figure out how to delete some entries from the datbase. What I wanted to do is add a button in each result that will have the value "delete"... but I cant figure out how to do this. Im kinda new to mysql. I just want it so when I click the button the result will get deleted from the database.
I did some research on this but I cant really grasp the examples. Can anybody help me out with this one? Thanks! Similar TutorialsHi all. Here is my scripts which allow user to check multiple rows of data and delete it , but it require select data and click for twice to delete the rows , what should be the error? Code: [Select] <form name="frmSearch" method="post" action="insert-add.php"> <table width="600" border="1"> <tr> <th width="50"> <div align="center">#</div></th> <th width="91"> <div align="center">ID </div></th> <th width="198"> <div align="center">First Name </div></th> <th width="198"> <div align="center">Last Name </div></th> <th width="250"> <div align="center">Mobile Company </div></th> <th width="100"> <div align="center">Cell </div></th> <th width="100"> <div align="center">Workphone </div></th> <th width="100"> <div align="center">Group </div></th> </tr> </form> <? echo "<form name='form1' method='post' action=''>"; while($objResult = mysql_fetch_array($objQuery)) { echo "<tr>"; echo "<td align='center'><input name=\"checkbox[]\" type=\"checkbox\" id=\"checkbox[]\" value=\"$objResult[addedrec_ID]\"></td>"; echo "<td>$objResult[addedrec_ID] </td>"; echo "<td>$objResult[FirstName]</td>"; echo "<td>$objResult[LastName] </td>"; echo "<td>$objResult[MobileCompany] </td>"; echo "<td>$objResult[Cell] </td>"; echo "<td>$objResult[WorkPhone] </td>"; echo "<td>$objResult[Custgroup] </td>"; echo "</tr>"; } echo "<td colspan='7' align='center'><input name=\"delete\" type=\"submit\" id=\"delete\" value=\"Delete\">"; if (isset($_POST['delete']) && isset($_POST['checkbox'])) // from button name="delete" { $checkbox = ($_POST['checkbox']); //from name="checkbox[]" $countCheck = count($_POST['checkbox']); for($d=0;$d<$countCheck;$d++) { $del_id = $checkbox[$d]; $sql = "DELETE from UserAddedRecord where addedrec_ID = $del_id"; $result2=mysql_query($sql) or trigger_error(mysql_error());;; } if($result2) { $fgmembersite->GetSelfScript(); } else { echo "Error: ".mysql_error(); } } echo "</form>"; Thanks for every reply. So, I just don't know where to post this question. I've written a quiz program where 50 English vocab words are pulled from a dB and displayed on one page with the order scrambled. My students then type the Spanish translation for each. When they submit the form the next page grades their work. They have to get a 90 or better for the grade to be automatically recorded, so I want them to click the back button and go back and make corrections. The problem is when they use a Chrome browser and click the back button the program re-sorts the order of questions. It leaves the order of their answers the same. So what they answered for number 1 is still in the field for number 1, but the questions (the English vocab word) is different. Chrome does this consistently so I thought this was a Chrome issue only. Then one of my students said the same thing happened to her when using Safari. So here is my question, how can I stop Chrome (or any other browser) from re-running my server-side PHP scripts (re-sorting the vocab array) when clicking the back button?
Here is the code for students taking the quiz:
<form method="post" action="portal.php?load=vquiz_grade" style="margin-left: 50px; line-height: 30px;">
$max = $count-1;
?>
//print "<br>";
<input type="hidden" name="max" value="<?print $max?>"> And here is the code showing them what they missed.
<?
// Total grade
print "You missed ".$wcount." words.<br>";
print "<table>";
// Grade response and set color
if ($wrong == 1){ if ($grade >= 90){
$query = "SELECT * FROM inno_vocab_assignments WHERE key_code = '$key_code' AND uname = '$secure_uname' AND teacher = '$teacher'";
// Prevent student from changing vocab list so as to do an easier list
// Insert grade
}
Thank you!
So I am trying to execute an sql query by clicking a button or a link. Ultimately I want users to be able to click the "Fav" button and it then fades into "Added to favorites!" (I am building a favorite system which first collects data on page load like userid and itemid and then it needs to send it to the DB after a button is clicked) The fade and stuff is not the most important part now (although a tip on doing that would be awesome) but the most important part is how to get this functional: PHP Code: <?php // Start Favorite System! $user =& JFactory::getUser(); $userid = $user->id; if ($userid == 62) { echo "userID: ".$userid."<p />"; if ($user->guest) {echo "You are a guest<p />";} $itemid = $this->item->id; echo "itemID: ".$itemid."<p />"; $catid= $this->item->category->id; echo "catID: ".$catid."<p />"; $query = "INSERT INTO jos_k2_fav_xref (userID, itemID, catID) VALUES ('$userid', '$itemid', '$catid')"; // Need a way to make this into a button $run = mysql_query($query) or die(mysql_error()); } else {} ?> Currently all the values get stored in the DB as the page is loaded. I however want to be able to click on something to execute that query how do i do that? I read a bunch of stuff on javascript and ajax but it got me nowhere... Help is greatly appreciated!

Hi i am working one of my assignment for school.. i just studied php.. my problem is, is it possible to load another form once i clicked a radio button? if its a yes... can you teach me how to do that? thank you! Folks,
Look at this weird thing. I load the page and get echoed as expected: Did Not REQUEST_METHOD! Then, I click the SUBMIT button and to my astonishment I get echoed: Did Not POST->Submit! Got 2 buttons. Same result whenever clicking any. Why is that ? Check it out:

ini_set('error_reporting',E_ALL);//Same as: error_reporting(E_ALL);
ini_set('display_errors','1');

Any idea ?? I have a download-list, and want to have a delete-button/link at each file. I have tried different codes, but i'm new to php and need some help. if ($handle = opendir('files/engelsk/')) { while (false !== ($file = readdir($handle))) { if ($file != "." && $file != "..") { $en .= '» <a href="/files/engelsk/'.$file.'">'.$file.'</a> - <i><a href="#">Delete file</a></i><br />'; } } closedir($handle); } It's the "<a href="#">Delete file</a>" I want to be the delete-button. Please help! Hi,
So I have a private page where I have a delete button.
The delete button just links to a page something like this: mysite.com/?postid=123&confirm=1 When confirm is set, the page is deleted.
The problem is, a malicious person could reverse engineer the URL and trick (logged in) users of the site into clicking the link.
How can I verify that the last page visited was from my site, in the private section?
Possible solutions:
I was thinking HTTP_REFERER (mispelled due to html standard stupidity), but heard it's not robust.
Right now I'm just setting a cookie for 1 minute, to limit the likelihood of hacking, but wonder if there is a better way.
Hi, I'm new to the forum so this could go in the MySQL section but I'm not sure. I am trying to make a page that will list all records from a column in HTML table and have a delete button to remove a specific record. I have got to the part where I have listed the records in a table. Note: Only records from a specific column ('links') are printed. Here is the code: Code: [Select] $con = mysql_connect("localhost","***","***"); if (!$con) { die('Could not connect: ' . mysql_error()); } mysql_select_db("***", $con); $result = mysql_query("SELECT * FROM main"); echo "<table border='1'> <tr> <th>Current links</th> </tr>"; while($row = mysql_fetch_array($result)) { echo "<tr>"; echo "<td>" . $row['links'] . "</td>"; echo "</tr>"; } echo "</table>"; mysql_close($con); How would I go about adding a delete button next to each record to delete that specific record? Thanks for any help. Hi, I'm doing a simple e-mail using localhost, while doing the rest, I realized I need a delete button for it. Is there a simple way to delete the message when the user opens the mail content?

I have searched the net inside and out and have tried many things. My problem is that I am trying to remove a line from an array by clicking a delete button. The outpur I need is: a line of text that comes from my text file after it is exploded into an array | With a delete button here next line of text that comes from my text file after it is exploded into an array | With a delete button here etc I have managed to write this much myself - Code: [Select] <?php $file = fopen('fav/fav.txt', 'r'); $file = file_get_contents('fav/fav.txt'); $file_array = explode("\n",$file); array_pop($file_array); foreach($file_array as $line) { echo "<form method='post' action=''>".$line. "<input type='submit' name='post' value='delete'><br>"; $fh = fopen("fav/fav.txt",'w'); foreach ($file_array as $line) { fwrite($fh,$line."\n"); } fclose($fh); } ?> The array_pop deletes from the bottom instead of the line the button is next too, I realise I will need to use and if statement but this is the closest I have gotten. Thanks in advance!!! I am new to php and I thought it best to start by using a CMS and creating small functions to extend it's functionality. I will start by explaining the situation around what I want to do. I am trying to create a module for the drupal CMS. The module I am trying to create I am creating for my girlfriends son (for when it is complete he will be the one maintaining it through the web interface). He wants a game server (WOW) and a web site that once they create an account on the web site it will create an account on the game server as well. If I understand the way this works correctly for this game server to work you need a logon database and then a character and world database for each realm you have. With that basically what happens is you go to the drupal web site and click create account, input a username, email address and password and agree to terms of service. Then drupal does some checks and writes the information to the drupal database and with the module I creating it will write to the logon database as well. I am working on the admin forms so you can edit how many realms the server has the sql statement to login to the game and add and delete realms. I have been looking at an example of a form for drupal here http://drupal.org/node/717746 but have converted it to my purpose and it brings up some questions here is what I have so far: function wowcp_gameserver_settings($form_state) { $form['server'] = array( '#type' => 'fieldset', '#title' => t('WOW Game Server Core'), ); $form['server']['decision'] = array( '#type' => 'select', '#title' => 'Select the Server Core that your WOW server runs on', '#options' => array('TrinityCore2', 'ArcEMU', 'Aspire', 'Mangos'), '#default_value' => TrinityCore2, ); $form['server']['sql_command'] = array( '#type' => 'textfield', '#title' => 'Select the SQL command for your server core', '#size' => 150, ); $form['server']['max_realms'] = array( '#type' => 'textfield', '#title' => t('Select the maximum realms allowed'), '#size' => 2, ); $form['logon'] = array( '#type' => 'fieldset', '#title' => t('WOW Game Server LOGON database setup') ); $form['logon']['logon_db'] = array( '#type' => 'textfield', '#title' => t('Enter the name of the LOGON database'), '#size' => 25, ); $form['logon']['logon_username'] = array( '#type' => 'textfield', '#title' => t('Enter the username for the LOGON database'), '#size' => 25, ); $form['logon']['logon_password'] = array( '#type' => 'textfield', '#title' => t('Enter the password for the LOGON database'), '#size' => 25, ); $form['realm']['character'] = array( '#type' => 'fieldset', '#title' => t('WOW Game Server first realm'), ); $form['realm']['character']['character_db'] = array( '#type' => 'textfield', '#title' => t('Enter the name of the CHARACTER database'), '#default_value' => $form_state['values']['character_db'], '#size' => 25, ); $form['realm']['character']['character_username'] = array( '#type' => 'textfield', '#title' => t('Enter the username for the CHARACTER database'), '#default_value' => $form_state['values']['character_username'], '#size' => 25, ); $form['realm']['character']['character_password'] = array( '#type' => 'textfield', '#title' => t('Enter the password for the CHARACTER database'), '#default_value' => $form_state['values']['character_password'], '#size' => 25, ); $form['realm']['world']['world_db'] = array( '#type' => 'textfield', '#title' => t('Enter the name of the WORLD database'), '#defaule_value' => $form_state['values']['world_db'], '#size' => 25, ); $form['realm']['world']['world_username'] = array( '#type' => 'textfield', '#title' => t('Enter the username for the WORLD database'), '#defaule_value' => $form_state['values']['world_username'], '#size' => 25, ); $form['realm']['world']['world_password'] = array( '#type' => 'textfield', '#title' => t('Enter the password for the WORLD database'), '#defaule_value' => $form_state['values']['world_password'], '#size' => 25, ); if (isset($form_state['storage']['new_name'])) { $form['character2'] = array( '#type' => 'fieldset', '#title' => t('WOW Game Server CHARACTER database setup for realm2'), ); $form['character2']['character_db2'] = array( '#type' => 'textfield', '#title' => t('Enter the name of the CHARACTER database for relam2'), '#default_value' => $form_state['values']['character_db2'], '#size' => 25, ); $form['character2']['character_username2'] = array( '#type' => 'textfield', '#title' => t('Enter the username for the CHARACTER database for realm2'), '#default_value' => $form_state['values']['character_username2'], '#size' => 25, ); $form['character2']['character_password2'] = array( '#type' => 'textfield', '#title' => t('Enter the password for the CHARACTER database for realm2'), '#default_value' => $form_state['values']['character_password2'], '#size' => 25, ); $form['world2'] = array( '#type' => 'fieldset', '#title' => t('WOW ame Server WORLD database setup for realm2'), ); $form['world2']['world_db2'] = array( '#type' => 'textfield', '#title' => t('Enter the name of the WORLD database for realm2'), '#defaule_value' => $form_state['values']['world_db2'], '#size' => 25, ); $form['world2']['world_username2'] = array( '#type' => 'textfield', '#title' => t('Enter the username for the WORLD database for realm2'), '#defaule_value' => $form_state['values']['world_username2'], '#size' => 25, ); $form['world2']['world_password2'] = array( '#type' => 'textfield', '#title' => t('Enter the password for the WORLD database for realm2'), '#defaule_value' => $form_state['values']['world_password2'], '#size' => 25, ); } $form['submit'] = array( '#type' => 'submit', '#value' => 'Submit', ); $form['clear'] = array( '#type' => 'submit', '#value' => 'Reset', '#validate' => array('wowcp_form_clear'), ); if (empty($form_state['storage']['new_name'])) { $form['new_name'] = array( '#type' => 'submit', '#value' => 'Add Realm', '#validate' => array('wowcp_form_new_name'), ); $form['delete'] = array( '#type' => 'submit', '#value' => 'Delete Realm', '#validate' => array('wowcp_form_delete'), ); } return $form; } If max_realms is set to a large number the way I see it you would have to hard code everything into the php file. Instead of that could you not remove from the if(isset) and have it that when they click on the add realm button check to make sure the textfield contains a number if it doesn't return an error if it does contain a number make sure it is not greater then max_realms and then use a start count and adding that number to all the arrays for that realm and validate all the information is what you expect. I think this would work for adding realms, I think where the problem would come in is in deleting realms (or it could be me over thinking it). For example if you have max_realms set to 4 you could have 5 the one default one that can't be deleted plus 4 others and the ones that can be deleted would be called realm1 - realm4 if you delete the first 2 you would minus count by 2 so if you clicked add realm again it would try and create realm3 which already exists. Is there another way on doing this that you could create the realms and delete them and it not try to add realms with the same array name? I have a dynamic script and need to create a click event function with JavaScript to delete the row which has a checkbox checked when the delete button is pressed. This is being implemented with PHP and as now serves as light code for this matter at hand. I was only able to delete all rows. I have my efforts with the js functions too. <script type="text/javascript"> var counter = 1; var limit = 6; function addTextArea() { if (counter == limit-1) { alert("Maximum limit " + counter + " sorry"); return false; } else { <!-- CAUTION THIS IS BACKWARDS. --> var newdiv = document.createElement('div'); newdiv.innerHTML = "" + (counter + 1) + " <br><textarea name='fav_det[]' id=counter rows='3' cols='20'>"; document.getElementById('div6').appendChild(newdiv); var newdiv = document.createElement('div'); newdiv.innerHTML = "" + (counter + 1) + " <br><textarea name='fav_col' id=counter rows='3' cols='20'>"; document.getElementById('div5').appendChild(newdiv); var newdiv = document.createElement('div'); newdiv.innerHTML = "" + (counter + 1) + " <br><textarea name='fav_mod[]' id=counter rows='3' cols='20'>"; document.getElementById('div4').appendChild(newdiv); var newdiv = document.createElement('div'); newdiv.innerHTML = " " + (counter + 1) + " <br><input type='text' name='truck[]' id=counter>"; document.getElementById('div3').appendChild(newdiv); var newdiv = document.createElement('div'); newdiv.innerHTML = " " + (counter + 1) + " <br><input type='text' name='car[]' id=counter>"; document.getElementById('div2').appendChild(newdiv); var newdiv = document.createElement('div'); newdiv.innerHTML = "" + (counter + 1) + " <br><input type='checkbox' name='chk[]' id=counter>"; document.getElementById('div1').appendChild(newdiv); counter++ return true; } } </script> <script type="text/javascript"> function deleteRowS(dataTable) { for (var rowi= table.rows.length; rowi-->0;) { var row= table.rows[rowi]; var inputs= row.getElementsByTagName('dataTable'); for (var inputi= inputs.length; inputi-->0;) { var input= inputs[inputi]; if (input.type==='checkbox' && input.checked) { row.parentNode.removeChild(row); break; } } } } </script> <script type="text/javascript"> function deleteRow() { var table = document.getElementById(tableID).tBodies[0]; var rowCount = table.rows.length; // var i=1 to start after header for(var i=1; i<rowCount; i++) { var row = table.rows[i]; // index of td contain checkbox is 8 var chkbox = row.cells[6].getElementsByTagName('input')[0]; if('checkbox' == chkbox.type && true == chkbox.checked) { table.deleteRow(i); } } }</script> </head> <table> <tr><td valign='top'><b>NEED DELETE ROW WITH CHECKBOX FUNCTION:</td></tr> </table> <table id="dataTable" width="auto" style="margin:-4px 0 0 0; padding:14px 0 0 0;" cellspacing="10px"><tbody id="dataTable"></tbody> <tr> <td valign='Top'> ✗ <div id="div1"> <input type="checkbox" name="chk[]" autocomplete="off" id="1" > </div> </td> <td valign='Top'> cars <div id="div2"> <input type="text" name="car[]" id="2" > </div> </td> <td valign='Top'> trucks <div id="div3"> <input type="text" name="truck[]" id="3" > </div> </td> <td valign='Top'> your favorite model <div id="div4"> <textarea name="mod[]" id="4" rows="3" cols="20"></textarea> </div> <br><br> </td> <td valign='Top'> your favorite add-ons <div id="div5"> <textarea name="fav_col" id="5" rows="3" cols="20"></textarea> </div> </td> <td valign='Top'> explain vehicle overall <div id="div6"> <textarea name="fav_det" id="6" rows="3" cols="20"></textarea> </div> </td> </tr> </table> <input type="button" value="Add another" onClick="addTextArea();" /> <input type="button" value="Delete row" onclick="deleteRow('dataTable');deleteRowS('dataTable')" /> Hello,
First of all I'd like to say thank you for all the great information on the forums, I've been reading a lot on here lately.
I've started to make a website where users can log in and submit items to a database, which is then displayed on another page.
If Tom and Bill both post 10 items, all 20 items will be displayed on the "listings" page, however on the main log in screen Tom will only see his own 10 items and Bill will see his own 10 items.
This is all working perfectly, however, I now need to add a delete button so that they can delete specific items.
I have loosely followed this tutorial here to get the table to display as I want it (amongst a few other things, such as the user logins) http://www.wickham43...mphptomysql.php
I've added the delete button in the PHP loop for each row, I just can't figure out how to delete the specific row when clicked.
Any help would be really appreciated
