IS THIS THE CORRECT CODE ???????????
<?php $host="localhost"; // Host name $username=""; // Mysql username $password=""; // Mysql password $db_name="test"; // Database name $tbl_name="test_mysql"; // Table name // Connect to server and select databse. mysql_connect("$host", "$username", "$password")or die("cannot connect"); mysql_select_db("$db_name")or die("cannot select DB"); $sql="SELECT * FROM $tbl_name"; $result=mysql_query($sql); $count=mysql_num_rows($result); ?> <table width="400" border="0" cellspacing="1" cellpadding="0"> <tr> <td><form name="form1" method="post" action=""> <table width="400" border="0" cellpadding="3" cellspacing="1" bgcolor="#CCCCCC"> <tr> <td bgcolor="#FFFFFF"> </td> <td colspan="4" bgcolor="#FFFFFF"><strong>Delete multiple rows in mysql</strong> </td> </tr> <tr> <td align="center" bgcolor="#FFFFFF">#</td> <td align="center" bgcolor="#FFFFFF"><strong>Id</strong></td> <td align="center" bgcolor="#FFFFFF"><strong>Name</strong></td> <td align="center" bgcolor="#FFFFFF"><strong>Lastname</strong></td> <td align="center" bgcolor="#FFFFFF"><strong>Email</strong></td> </tr> <?php while($rows=mysql_fetch_array($result)){ ?> <tr> <td align="center" bgcolor="#FFFFFF"><input name="checkbox[]" type="checkbox" id="checkbox[]" value="<? echo $rows['id']; ?>"></td> <td bgcolor="#FFFFFF"><? echo $rows['id']; ?></td> <td bgcolor="#FFFFFF"><? echo $rows['name']; ?></td> <td bgcolor="#FFFFFF"><? echo $rows['lastname']; ?></td> <td bgcolor="#FFFFFF"><? echo $rows['email']; ?></td> </tr> <?php } ?> <tr> <td colspan="5" align="center" bgcolor="#FFFFFF"><input name="delete" type="submit" id="delete" value="Delete"></td> </tr> <? // Check if delete button active, start this if($delete){ for($i=0;$i<$count;$i++){ $del_id = $checkbox[$i]; $sql = "DELETE FROM $tbl_name WHERE id='$del_id'"; $result = mysql_query($sql); } // if successful redirect to delete_multiple.php if($result){ echo "<meta http-equiv=\"refresh\" content=\"0;URL=delete_multiple.php\">"; } } mysql_close(); ?> </table> </form> </td> </tr> </table> Similar TutorialsSo here's what i want to do: i have 2 checkboxes, when Checkbox A is checked, i want to automatically check the checkbox B. When A is unchecked, then uncheck B how can i do that? thanks a lot ! Hi, If I have two check-boxes and one is already checked and then the is checked, how would I get it to uncheck the first one using JavaScript. Thanks, Cs1h Hi, here's the code Code: <div class="artworkdelete"> <a href="javascript:void(0);" id="del_<?=$artworkDetails['artwork_id'] ?>_<?=$temp_cat_id; ?>" onclick="deleteThisArtWork(this.id)">Delete</a> </div> that's actually a "Delete" link , when I click it, there's a some sort of loading animation like stuff , similar to the thing that appears when one clicks the edit button of a thread here in this forum..then and it deletes the data and doesn't need to refresh the page, i guess it is ajax.....it's not my code.. now I was asked to alter it and use a pop up box to ask the clicker "Yes" or "No" before deleting the data , what or how to change that code snippet i pasted above ? Hi all! I created a form where users are allowed to delete a specific row of data by clicking the "cancel" button from the drop down menu. However, I have a problem deleting my data using the javascript. Apparently, I only able to delete the first row of the data but not for the rest! The following is the code i have: PHP Code: <html> <body style="background-color:#E0FFFF;"> <script language="javascript" > <!-- hide function submitRequest(val) { document.forms[0].submit(); } // end hide --> </script> <?php $con = mysql_connect("localhost","root",""); if (!$con) { die('Could not connect: ' . mysql_error()); } mysql_select_db("my_course", $con); $result = mysql_query("SELECT * FROM Courses ORDER BY Year, Sem, CourseCode"); $result1 = mysql_query("SELECT * FROM Courses ORDER BY Year, Sem, CourseCode"); echo "<table border='1' cellpadding='2' cellspacing='0'> <tr> <th>CourseCode</th> <th>CourseName</th> <th>Year</th> <th>Sem</th> <th>Grade</th> <th>Option</th> </tr>"; ?> <?php while($row = mysql_fetch_array($result)) { echo "<tr>"; echo "<td>" . $row['CourseCode'] . "</td>"; echo "<td>" . $row['CourseName'] . "</td>"; echo "<td>" . $row['Year'] . "</td>"; echo "<td>" . $row['Sem'] . "</td>"; echo "<td>" . $row['Grade'] . "</td>"; echo "<td>"; ?> <?php ?> <form name="form1" action="submitDelete.php" method="post"> <select name="cancel" onchange="submitRequest(this.value);"> <option value=> </option> <option value="<?php echo $row['CourseName'];?>">Cancel</option> </select> </form> <?php echo "</td>"; echo "</tr>"; } echo "</table>"; mysql_close($con); ?> <br/> <br/> </body> </html> Thanks in advance! Hello, I have something like this: Code: function asd() {
var timeout = setInterval('alert(\'asd\')', 3000);
}
function asd2() {
// with this function I want to remove the interval of 3 seconds for variable timeout.
}
I have variable timeout and with the second function asd2() I want to remove this variable. The js line... delete new Obj(); brings my script to a halt in IE7. the error in the MS-VWD debugger is... "Cannot delete 'new rect()". The same line seems to work fine in FF. If I change the code to... var o = new Obj(); delete o; - all works fine in IE. Can someone explain why this occurs? btw... the actual code is something like... delete new rect().getElem(elem).hcenterInRect(parRect).setElem(elem); so there's a bunch of processing between the new and deleting of the object ("rect"). this is obviously not a big problem but i was just curious as to how IE was interpretting this line. thanks to any of you javascript wizards that may have a clue. I am trying to delete or hide better to say advertisment on Forumotion forum. http://testforum-lolz.serbianforum.info/ When you use firebug to inspect you can find this: Code: html body .w74704f, html body .w74704f iframe, html body iframe[name="google_ads_frame"], html body .w74704f iframe[name="google_ads_frame"], html body #wrap #page-body div.w74704f, html body #page-body .w74704f {

When i type display:none; in every single code so I can hide it it doesent work. I dont know can there be any javascript for it. Maybe this can help: Delete this post. Thank you

hi I do not know why the cookies can't be deleted Code: function deleteCookies()
{
var splitC=document.cookie.split(";");
var i;
for(i=0;i<splitC.length;i++)
{
var getName=splitC[i].split("=");
var cookieDelete = getName[0].replace(/^\s+|\s+$/g, '');
document.cookie=cookieDelete+"=0;expires=Thu, 01-Jan-70 00:00:01 GMT";
}
}
This function is part of a page that will delete a product that a customer has selected. The question I have is what is the line line that actually removes the item from the list of products chosen? From my understanding, in order to establish an array, new array = elements[i] has to be added but Im thinking that elements[i] is the array that holds the product. Does the "0" in this line actually delete the item? document.template.elements[i].value = 0 ; Code: function del_item(X,msg) {
// var msg = "Are you sure you want to delete this line item?"
resp = confirm("Are you sure you want to " + msg + "?") ;
if (resp) {
var len = document.template.elements.length
//loop to put into arrays
for (var i = 0; i < len; i++) {
var lname = document.template.elements[i].name ;
if(lname == X) {
document.template.elements[i].value = 0 ;
process_order(0) ;
document.template.loginpath.value = "CO" ;
document.template.submit() ;
}
}
} else {
return ;
}
}
I found a very intressting JS function at this webpage: http://www.dynamicdrive.com/dynamici...edcollapse.htm I wonder if someone knows wihich part from the JS-file i should change/delete so i only get the fade at exempel 1 and not the slide/rolling effect. I only want the fade. The JS is: Code: //** Animated Collapsible DIV v2.0- (c) Dynamic Drive DHTML code library: http://www.dynamicdrive.com.
//** May 24th, 08'- Script rewritten and updated to 2.0.
//** June 4th, 08'- Version 2.01: Bug fix to work with jquery 1.2.6 (which changed the way attr() behaves).
//** March 5th, 09'- Version 2.2, which adds the following:
//1) ontoggle($, divobj, state) event that fires each time a DIV is expanded/collapsed, including when the page 1st loads
//2) Ability to expand a DIV via a URL parameter string, ie: index.htm?expanddiv=jason or index.htm?expanddiv=jason,kelly
//** March 9th, 09'- Version 2.2.1: Optimized ontoggle event handler slightly.
//** July 3rd, 09'- Version 2.4, which adds the following:
//1) You can now insert rel="expand[divid] | collapse[divid] | toggle[divid]" inside arbitrary links to act as DIV togglers
//2) For image toggler links, you can insert the attributes "data-openimage" and "data-closedimage" to update its image based on the DIV state

I have been searching the internet for thhe past hour trying to find this and searched this forum, I am trying to Delete my cookie with a button. On my websitr I have a cookie to remember the name of the user, I want them to be able to change their name with a button. so delete cookie. How can this be done? The cookie names its seld "UserName" if this helps. Hi I am working on a .net basket where I save the info for the products in the basket etc in a cookie. Now I have an html button on the basket page where I want to be able to delete the product (Cookie). I am using Code: <script type="text/javascript"> function delete_cookie ( cookie_name ) { expires = Now(); document.cookie = cookie_Name+"= ;expires="+expires.toGMTString(); } </script>But I get an error that says the cookie is not delcared? But it does exist because I retrive the name of the cookie when looping through the cookie list. What am I doing wrong here? Greetings: On the click of a button, how would I delete a certain record in a database table, w/o refreshing the page? I am new to JS and don't even know where to start. Thanks in advance. Have the followig questions and need answers regarding the following script that will Preview a Photo before upload. The script is from http://jsbin.com/uboqu3/edit#javascript,html 1) The script works for Firefox, no good for IE. How to make it works for IE? 2) It does not have a method to delete the photo. Needs something like a small image "X" installed on the Preview Photo, clicking this "X" will delete the photo. Can anyone supply this solution? Code: <!DOCTYPE html>

Hello, I have a script that lets you add tasks to a task list and then you can click a button to sort them, but I cannot get the "Delete Selected Task" and "Delete All Tasks" buttons to work correctly. I will be eternally indebted to whoever can help me fix these two buttons. The code I am working on is posted below. Thank you for your time.

Is that it ? I can't have delete ? Or can this be written in some other way, including delete ? I have a HTML table with 800 rows. How can I delete rows that has no Activity & no $ in JavaScript(Orange Colored Rows)? Please note I can have 1 or more than 1 assessments with 1 or more than 1 activity. Sample data.
