The insert and delete functions are working fine. The $submit variable is being passed 'Update' ~ that is working. This is some extremely old code that has migrated to a new server and is no longer working. Code: [Select] <?php $id = $_GET["id"]; $delete = $_GET["submit"]; $sortorder = $_POST["sortorder"]; $name = $_POST["name"]; $content = $_POST["content"]; $submit = $_POST["submit"]; require'../include/maindb.php'; if($submit=="Submit") { $sql="INSERT INTO biography (id, sortorder, name, content) VALUES (NULL, '".$sortorder."', '".nl2br(addslashes(trim($name)))."', '".htmlentities(addslashes(trim($content)))."')"; } if ($submit == "Update") { $sql="UPDATE biography SET sortorder='".$sortorder."', name='".nl2br(addslashes(trim($name)))."', content='".htmlentities(addslashes(trim($content)))."' WHERE id='".$id."'"; } if ($delete=="Delete") { $sql="DELETE FROM biography WHERE id='".$id."'"; } mysql_query($sql); echo(mysql_error()); header('Location: index.php'); ?> Hi guys, Doing a small project and i'm pretty new to php/mysql so hoping someone can help. Also i wasn't sure if this should be in php section or mysql, so apologises if it's in the wrong section. Basically... I have a form with a table in it with the fields (id, model, current stock level, new stock level) The table is populated using a mysql query to get the data from 1 table in a database. In the new stock column there's a simple text box to put a number in. Sooo like (ID) (Model) (current stock level) (new stock level) 1 AAA 3 [ ] 2 BBB 1 [ ] 3 CCC 4 [ ] A user will then put a new number in the 'new stock level' text box and when it gets submitted the new number replaces the number in 'current stock level' Basically i know how to do it if it was just the one record, but how do i get it to update all the ones with numbers in the new stock level column at the same time, and ignore it if it doesn't have anything entered in the text box? appreciate any help! thanks! Hi, I have a simple mySQL database and I would like to update using a simple html form. One of the field is "accepted" and is type "boolean". I have a texbox where I will write the record id and another button which will change the "accepted" value from 0 to 1 for that record id. The problem is that I don't know how to start.... Thanks in advance Sergio My form has 40 fields, and I want to re-generate it to be reviewed as it was when submitted. Next, I want to be able to UPDATE the forms values, where necessary. Is there an easy way to UPDATE the entire form from the reviewable version. Is it smarter to update ONLY the specific items that need modification? Any examples would be helpful. Anyone have any idea what I did wrong this time? This is def where my problem is Code: [Select] // UPDATE THE RECORD WITH THE CURRENT FORM DATA $edit_query_insert="UPDATE client_information SET account_number = '$account_number', name_first = '$name_first', name_last = '$name_last', address = '$address', city = '$city', state = '$state', zipcode = '$zipcode', telephone = '$telephone', telephone_alt = '$telephone_alt', email = '$email'"; This is the code for the page itself: Code: [Select] // SELECT THE DATABASE mysql_select_db("terra_elegante_operations", $con); // GET THE FORM DATA FROM PREVIOUS PAGE // ASSIGN NEW VARIABLES $account_number = $_POST['account_number']; $name_first = $_POST['name_first']; $name_last = $_POST['name_last']; $address = $_POST['address']; $city = $_POST['city']; $state = $_POST['state']; $zipcode = $_POST['zipcode']; $telephone = $_POST['telephone']; $telephone_alt = $_POST['telephone_alt']; $email = $_POST['email']; // UPDATE THE RECORD WITH THE CURRENT FORM DATA $edit_query_insert="UPDATE client_information SET account_number = '$account_number', name_first = '$name_first', name_last = '$name_last', address = '$address', city = '$city', state = '$state', zipcode = '$zipcode', telephone = '$telephone', telephone_alt = '$telephone_alt', email = '$email'"; if (!mysql_query($edit_query_insert,$con)) { die('Error: ' . mysql_error()); } ?> <table border="0" cellspacing="0" cellpadding="3" width="960" bordercolor="#000000"> <tr> <td valign="top" width="50%"><!-- Open Main left Cell --><table border="0" cellspacing="0" cellpadding="1" width="100%" bordercolor="#000000"><tr><td colspan="4"><B>CLIENT PROFILE</B></td></tr> <?php // Query & assign to the $client_information table. $get_client_information = "SELECT * from client_information where account_number = $account_number"; $client_information = mysql_query($get_client_information) or die (mysql_error()); // The Array & Output - Included HTML Output here for $client_information while ($row = mysql_fetch_array($client_information)) { ?> <tr> <td width="30%"><font face="verdana" size="2" color="#000000">Account Number:</font></td><td colspan="2"><font face="verdana" size="2" color="#000000"><?php echo $row['account_number']; ?></font></td> </tr> <tr> <td><font face="verdana" size="2" color="#000000">Last Name:</font></td><td><font face="verdana" size="2" color="#000000"><?php echo $row['name_last']; ?></font></td> </tr> <tr> <td><font face="verdana" size="2" color="#000000">First Name:</font></td><td><font face="verdana" size="2" color="#000000"><?php echo $row['name_first']; ?></font></td> </tr> <tr> <td><font face="verdana" size="2" color="#000000">Address:</font></td><td><font face="verdana"size="2" color="#000000"><?php echo $row['address']; ?></font></td> </tr> <tr> <td><font face="verdana" size="2" color="#000000">City:</font></td><td><font face="verdana" size="2" color="#000000"><?php echo $row['city']; ?></font></td> </tr> <tr> <td width="10%"><font face="verdana" size="2" color="#000000">State:<font></td><td><font face="verdana" size="2" color="#000000"><?php echo $row['state']; ?></font></td> </tr> <tr> <td><font face="verdana" size="2" color="#000000">Zipcode:</font></td><td><font face="verdana" size="2" color="#000000"><?php echo $row['zipcode']; ?></font></td> </tr> <tr> <td><font face="verdana" size="2" color="#000000">Telephone:</font></td><td><font face="verdana" size="2" color="#000000"><?php echo $row['telephone']; ?></font></td> </tr> <tr> <td><font face="verdana" size="2" color="#000000">Telephone 2:</font></td><td><font face="verdana" size="2" color="#000000"><?php echo $row['telephone_alt']; ?></font></td> </tr> <tr> <td><font face="verdana" size="2" color="#000000">E-mail</td></td><td><font face="verdana" size="2" color="#000000"><?php echo "<a class=\"bubble_nav\" href='mailto:?id=$row[email]'>$row[email]</a\>"; } ?></font></td> </tr> </table> <?php include('includes/footer.php'); ?> Hello,
Anyone can suggest me what is the best way to update table records. I'm kinda scared to make an update on a table because it may damage the system and I am not really good on SQL commands.
Right now I just made a process on PHP to update table records. It does update email records on but it stop because of the limit of loading the page. Is there anyway accurately update all the data of the table.
Here is what I want to achieve.
I have a table with an "email" field on it, those email data from "email" field on tb_one must be change to cID records base on tb_two.
tb_one
Field =
- id
- email
- etc.
tb_two
Field =
- id
- email (same as on tb_one)
- cID
Hi, I am trying to update the status of the record. I don't want to insert the record if not exists. I just want to know the update is success or not.

I have a form that stores data to a database. Separate from that page I would like to have another where at any given time a user can download a .csv of the most recent addition or two? If not a .csv, can they easily view the record without having to know mySQL / phpAdmin and such? Thanks! Jerry I have 2 tables, access_level and pages. In pages table i will have all the details of page like page_id, code, herf, pagename.. and i will select few from this table and store it in access_level table depending on the department and position. Now while editing, i will display all the pages which is stored in access_level pages with a particular page code along with those pages from pages table. if the page_id exists in access_level table, its has to get updated, if its not present then it should get inserted into access_level table.

Yesterday, I created a topic about how I could update records and I managed to achieve that successfully. Now I have another dilemma. When I have a specific record I want to update, I want to change a category ID of an product (e.g. change it from 1 to 2) but how do I go about doing this? Here is my code thus far: Code: [Select] <?php require_once ('./includes/config.inc.php'); require_once (MYSQL); $id=$_GET['prodID']; $results = mysqli_query($dbc, "SELECT * FROM product WHERE prodID=".$_GET['prodID'].""); $row = mysqli_fetch_assoc($results); ?> <form action="" method='POST'> Product ID: <input type="text" value="<?php echo $row['prodID'];?>" name="prodID" /> <br /> Product: <input type="text" value="<?php echo $row['product'] ;?>" name="product" /> <br /> Product Description: <input type="text" value="<?php echo $row['prod_descr'] ;?>" name="prod_descr" /> <br /> Category: <select name="category"> <option value="<?php echo $row['catID'];?>"></option> </select> Price: <input type="text" value="<?php echo $row['price'] ;?>" name="price" /> <br /> In Stock: <input type="text" value="<?php echo $row['stock'] ;?>" name="stock" /> <br /> <br /><input type="submit" value="save" name="save"> </form> <?php if(isset($_POST['save'])) { $id = $_POST['prodID']; $product = $_POST['product']; $descr = $_POST['prod_descr']; $price = $_POST['price']; $stock = $_POST['stock']; // Update data $update = mysqli_query($dbc, "UPDATE product SET product='$product', prod_descr='$descr', price='$price', stock='$stock' WHERE prodID=".$_GET['prodID'].""); header( 'Location: update_save.php' ) ; } ?> I am trying to get this query correct. I want to insert a record into the database upon form submission but only if the record does not already exist. If the record exists, then I want it to be updated in the database.
What is happening: Upon form submit, a new record is entered into the database every time. Note: The contact_id column is both primary key and unique in my database. Here is my code:
if($_POST['submit']){
$con=mysqli_connect("localhost","username","password","database_name");
// Check connection
if (mysqli_connect_errno())
{
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
$org = mysql_real_escape_string($_POST['organization']);
$namefirst = mysql_real_escape_string($_POST['firstName']);
$namelast = mysql_real_escape_string($_POST['lastName']);
$emailaddy = mysql_real_escape_string($_POST['email']);
$phonenum = mysql_real_escape_string($_POST['phone']);
$appquestion = mysql_real_escape_string($_POST['appquestion']);
$banner = mysql_real_escape_string($_POST['banner']);
$bulletin = mysql_real_escape_string($_POST['bulletin']);
$giveaway = mysql_real_escape_string($_POST['giveaway']);
$app = mysql_real_escape_string($_POST['app']);
$tshirt = mysql_real_escape_string($_POST['tshirt']);
$tshirtp = mysql_real_escape_string($_POST['tshirtp']);
$print = mysql_real_escape_string($_POST['print']);
$party = mysql_real_escape_string($_POST['party']);
$orgnotes = mysql_real_escape_string($_POST['notes']);
$sql="INSERT INTO database_name (contact_id, first_name, last_name, email_address, phone_number, org, appquestion, banner, bulletin, giveaway, app, tshirt, promised_tee, print, party, org_notes)
VALUES
('','$namefirst','$namelast','$emailaddy','$phonenum','$churchorg','$appquestion','$banner','$bulletin','$giveaway','$app','$tshirt','$tshirtp','$print','$party','$orgnotes')
ON DUPLICATE KEY UPDATE first_name = '$namefirst', last_name = '$namelast', email_address = '$emailaddy', phone_number = '$phonenum', org = '$org', appquestion = '$appquestion', banner = '$banner', bulletin = '$bulletin', giveaway = '$giveaway', app = '$app', tshirt = '$tshirt', promised_tee = '$tshirtp', print = '$print', party = '$party', org_notes = '$orgnotes'" ;
if (!mysqli_query($con,$sql))
{
die('Error: ' . mysqli_error($con));
}
echo "1 record added";
mysqli_close($con);
}
From everything I have read, I need to use ON DUPLICATE KEY UPDATE to replace the old information with new information in the database upon form submission. While the insert part of my code is working, the portion with ON DUPLICATE KEY UPDATE is not working.
Why might this portion of the code not be working? Is there a better way to insert else update the information?
Thank you for any help or guidance you can give me! I've been working on this concept for three days and have read a ton of information about it, but am still not able to get it to work.
Hi all, Im really struggling to build an update multiple records form, Ive built my table which calls all data i need from the db in a looped region which works fine I just cant understand how to then input these back into the table in the correct rows, if this makes sense? Ive been reading this tutorial but Its not very informative its more of a copy and paste http://www.phpeasystep.com/mysql/10.html Hello,
Here is my current code:
index.php
<html>
<body>
<form id="hey" name="hey" method="post" onsubmit="return false">
Name:<input type="text" name="name">
<input type="submit" name="submit" value="click">
</form>
<table class="table table-bordered" id="update">
<thead>
<th>Name</th>
</thead>
<tbody>
<script type="text/javascript">
$("#hey").submit(function() {
$.ajax({
type: 'GET',
url: 'response.php',
data: { username: $('#name').val()},
success: function (data) {
$("#update").prepend(data);
},
error: function (xhr, ajaxOptions, thrownError) {
alert(thrownError);
}
});
});
</script>
</tbody>
</table>
response.php
<?php $username = $_GET['username']; echo "<tr>"; echo "<td>$username</td>"; echo "</tr>"; ?>This code works fine, it prints out the rows as what the user enters. Now what I want to do is, log all these entries to a mySQL database and also, display these rows over the site. i.e., any user who is online, should be seeing this without having to refresh the page too.. Real time updates in a way. How can I achieve that? Thanks! |
