PHP - Altering Existing Table With Data
I have a table with lots of records. My table has the following field, with records containing either NULL or '1' that I need to modify.
Similar TutorialsHi, I am extracting data from a mysql db to then edit and update back into the db and use below to list items first - Code: [Select] <?php // Connect to server and select database. mysql_connect('localhost', 'xxxxxxxxx', 'xxxxxxxxxxxxx') or die("Error: ".mysql_error()); mysql_select_db("xxxxxxxxx"); $sql="SELECT * FROM properties"; $result=mysql_query($sql); ?> <table width="400" border="0" cellspacing="1" cellpadding="0"> <tr> <td> <table width="400" border="1" cellspacing="0" cellpadding="3"> <tr> <td colspan="4"><strong>List data from mysql </strong> </td> </tr> <tr> <td align="center"><strong>Name</strong></td> <td align="center"><strong>Lastname</strong></td> <td align="center"><strong>Email</strong></td> <td align="center"><strong>Update</strong></td> </tr> <?php while($rows=mysql_fetch_array($result)){ ?> <tr> <td><? echo $rows['Property_Rating']; ?></td> <td align="center"><a href="update.php?id=<? echo $rows['ID']; ?>">update</a></td> </tr> <?php } ?> </table> </td> </tr> </table> <?php mysql_close(); ?> I then go next page where I show data and allow editing - <?php // Connect to server and select database. mysql_connect('localhost', 'xxxxxxxxx', 'xxxxxxxxxxxxx') or die("Error: ".mysql_error()); mysql_select_db("xxxxxxxxx"); // get value of id that sent from address bar $id=$_GET['id']; // Retrieve data from database $sql="SELECT * FROM properties WHERE id='$id'"; $result=mysql_query($sql); $rows=mysql_fetch_array($result); ?> <table width="400" border="0" cellspacing="1" cellpadding="0"> <tr> <form name="form1" method="post" action="update_ac.php"> <td> <table width="100%" border="0" cellspacing="1" cellpadding="0"> <tr> <td> </td> <td colspan="3"><strong>Update data in mysql</strong> </td> </tr> <tr> <td align="center"> </td> <td align="center"> </td> <td align="center"> </td> <td align="center"> </td> </tr> <tr> <td align="center"> </td> <td align="center"><strong>Property_Name</strong></td> <td align="center"><strong>roperty_Rating</strong></td> <td align="center"><strong>Property_Address</strong></td> </tr> <tr> <td> </td> <td align="center"><input name="Property_Rating" type="text" id="Property_Rating" value="<? echo $rows['Property_Rating']; ?>"></td> </tr> <tr> <td> </td> <td><input name="id" type="hidden" id="id" value="<? echo $rows['id']; ?>"></td> <td align="center"><input type="submit" name="Submit" value="Submit"></td> <td> </td> </tr> </table> </td> </form> </tr> </table> <? // close connection mysql_close(); ?> And then the update page - <?php // Connect to server and select database. mysql_connect('localhost', 'xxxxxxxxx', 'xxxxxxxxxxxxx') or die("Error: ".mysql_error()); mysql_select_db("xxxxxxxxx"); // update data in mysql database $sql="UPDATE properties SET Property_Name='$Property_Name' WHERE id='$id'"; $result=mysql_query($sql); // if successfully updated. if($result){ echo "Successful"; } else { echo "ERROR"; } ?> Everything seems ok but when I edit the data and submit I get the success message but data not changed in db. Any ideas? Thanks. MOD EDIT: code tags added. Hi guys, im inserting data into the table using drop-down list & multi select list,well it works very well. but i need to make sure i should not insert same StudentID & CourseID twice. here my code for you could anyone tell me pls where should i write code to check existing data? <?php $con = mysql_connect("localhost","root",""); if (!$con) { die('Could not connect: ' . mysql_error()); } mysql_select_db("uni", $con)or trigger_error('MySQL error: ' . mysql_error()); $result = mysql_query("SELECT * FROM student") or trigger_error('MySQL error: ' . mysql_error()); echo '<select name="sid">'; while($row = mysql_fetch_array($result)) { echo '<option value="' . $row['StudentID'] . '">' . $row['StudentName'] . '</option>'; } echo '</select>'; // ---------------- ?> </div> <div class="style41" id="Layer7"> <?php $result = mysql_query("SELECT * FROM course") or trigger_error('MySQL error: ' . mysql_error()); echo '<select name ="cid[]" multiple="multiple" size="10">'; while($row = mysql_fetch_array($result)) { echo '<option value="' . $row['CourseID'] . '">' . $row['CourseName'] . '</option>'; } echo '</select>'; mysql_close($con); ?> ------------------------------------ <?php $con = mysql_connect("localhost","root",""); if (!$con) { die('Could not connect: ' . mysql_error()); } mysql_select_db("uni", $con)or trigger_error('MySQL error: ' . mysql_error()); if (!empty($_POST['sid']) && !empty($_POST['cid'])) { $ct = 0; $student = $_POST['sid']; foreach ($_POST['cid'] as $key => $course) { $sql = "INSERT INTO take (StudentID, CourseID) VALUES('".mysql_real_escape_string($student)."', '".mysql_real_escape_string($course)."')"; $query = mysql_query($sql) or trigger_error('MySQL error: ' . mysql_error()); if (mysql_affected_rows() > 0){$ct++;} } echo $ct . ' rows added.'; } mysql_close($con); ?> so I'm trying to change some specific columns in a row in a table of a MySQL database by calling the Doctrine_Query when an option is selected inside an admin panel of my website. Here are the details: Table name: chatUsers I need to find all rows with the person who has a username of: $chatUsers->username (The column inside chatUsers is called username) Once all those rows are found, change the value of all the row's column "type" to "user" Is this even possible? So far I have: [/list] Code: [Select] <?php function userChatReset(){ $query = Doctrine_Query::create()->update('db_chatUsers')->set('type', 'user')->where('username = '.$chatUsers->username); //execute query $rows = $query->execute(); echo $rows.' rows updated'; } ?> ...And I'm not sure where to go from there, or if that's even correct. Sorry in advance, I'm not very good with PHP yet. splobjectstorage.attach shows how to add an object inside the storage and associate it to some data. How should one replace the data associated to an object already in storage? All of the following solutions seem to work, however, I would like confirmation as I couldn't find and specific direction in the documentation. Assuming that detaching shown in my options 3 and 4 is not required, right? Probably option 2? Or, would it be best not to replace the data in storage, but add a shell object to the storage and update the data property? Use case is the object is a stream and the data is a specific type of client which can change over time.
<?php
class dataA{}
class dataB{}
class dataC{}
class dataD{}
class dataE{}
class obj{}
$storage = new SplObjectStorage();
$obj=new obj;
$storage->attach($obj, new dataA);
$data = $storage[$obj];
var_dump($data);
//Option 1
$storage->attach($obj, new dataB);
$data = $storage[$obj];
var_dump($data);
//Option 2
$storage->offsetSet($obj, new dataC);
$data = $storage[$obj];
var_dump($data);
//Option 3
$storage->detach($obj);
$storage->attach($obj, new dataD);
$data = $storage[$obj];
var_dump($data);
//Option 4
$storage->detach($obj);
$storage->offsetSet($obj, new dataE);
$data = $storage[$obj];
var_dump($data);
object(dataA)#3 (0) { } object(dataB)#4 (0) { } object(dataC)#3 (0) { } object(dataD)#4 (0) { } object(dataE)#3 (0) { }

function display($randomNr) This topic has been moved to MySQL Help. http://www.phpfreaks.com/forums/index.php?topic=348130.0 Im not much of a coder, and I obviously did this wrong since it is not working. Im trying to bring a new field value in to an existing php file. I created a new table, and an admin page to control that field. I cant, however, figure out how to use that value in a different php file. Actually, there are 2 files. Each using a different field from that new table.

Here's a simplified sample that I'm working with: -- Column 1 Column 2 Coloumn3 Sue Cat Adopted Jack Dog Adopted Cujo Dog Not Adopted -- The column I'm trying to scrub my loop against is column 3.

I have an existing GET form that I use and want to write to a MYSQL table everytime a user uses that form. Code: [Select] <FORM ACTION="https://someurl.com" METHOD=GET> Would the easiest to be a javascript function that uses the onclick event? What would be the best way to continue to pass the user along while capturing data and writing that to a MYSQL table. Thanks! Hello to all, I have problem figuring out how to properly display data fetched from MySQL database in a HTML table. In the below example I am using two while loops, where the second one is nested inside first one, that check two different expressions fetching data from tables found in a MySQL database. The second expression compares the two tables IDs and after their match it displays the email of the account holder in each column in the HTML table. The main problem is that the 'email' row is displayed properly while its while expression is not nested and alone(meaning the other data is omitted or commented out), but either nested or neighbored to the first while loop, it is displayed horizontally and the other data ('validity', 'valid_from', 'valid_to') is not displayed.'
Can someone help me on this, I guess the problem lies in the while loop? <thead> <tr> <th data-column-id="id" data-type="numeric">ID</th> <th data-column-id="email">Subscriber's Email</th> <th data-column-id="validity">Validity</th> <th data-column-id="valid_from">Valid From</th> <th data-column-id="valid_to">Valid To</th> </tr> </thead> Here is part of the PHP code:
<?php
while($row = $stmt->fetch(PDO::FETCH_ASSOC))
{
echo '
<tr>
<td>'.$row["id"].'</td>
';
while ($row1 = $stmt1->fetch(PDO::FETCH_ASSOC)) {
echo '
<td>'.$row1["email"].'</td>
';
}
if($row["validity"] == 1) {
echo '<td>'.$row["validity"].' month</td>';
}else{
echo '<td>'.$row["validity"].' months</td>';
}
echo ' <td>'.$row["valid_from"].'</td>
<td>'.$row["valid_to"].'</td>
</tr>';
}
?>
Thank you. I can add and delete data from my table. Now I need to be able to change one or more fields in an entry. So I want to retrieve a row from the db, display that data on a form where the user can change any field and then pass the changed data to an update.php program. I know how to go from form to php. But how do I pass the data from retrieve.php to a form so it will display? Do I use a URL and Get? Can I put the retrieve and form in the same program? Hi! I am creating a small project somewhat like a photo gallery as my first practice page. I just would like to know how can I alter photos or file in php. Or should I just do a delete and then upload a new one? Thanks in advance... Hey everyone. I am creating a website so my family can select from the list of present my daugther has asked for. I have them logging in, and that works. I have the table data set and the search and table display works. But I would like to display the list (as in the code below) but with a checkbox in the first column (add a column). From that the authenticated user can click on the item they have purchased and that selection will be moved to another table (called purchased). I have that code. The only thing I cannot figure out is to present the data in list form with a checkbox (like you would see on an order form).

Similar to wordpress except simpler like setting a default email for error messages or something. The idea is that it's used as an installation script for web-ware where someone fills in a form with their database details, my script will hard-code them into the settings file and then delete itself. I'll admit I did get the idea from wordpress. Only the way it's coded currently requires a certain combination of characters at the end and seems really messy. The script looks like this (and does work): $endpos = strpos ( $contents, '"; //replace with name//', $startpos); The settings file looks like this: $hard_name = "Smith"; //replace with name// As you can see I use the comment in the settings file, which follows what I'm actually changing, to find the end of the variable. I am sure there must be a better way of doing things but don't know what. It just seems really inefficient because if the comment is removed the script breaks. Any info and tips would be much appreciated. IceKat I found this online at http://php.net/manual/en/function.time.php: <?php function rel_time($from, $to = null) { $to = (($to === null) ? (time()) : ($to)); $to = ((is_int($to)) ? ($to) : (strtotime($to))); $from = ((is_int($from)) ? ($from) : (strtotime($from))); $units = array ( "year" => 31536000, // seconds in a year (12 months) "month" => 2628000, // seconds in a month (4 weeks) "week" => 604800, // seconds in a week (7 days) "day" => 86400, // seconds in a day (24 hours) "hour" => 3600, // seconds in an hour (60 minutes) "minute" => 60, // seconds in a minute (60 seconds) "second" => 1 // 1 second ); $diff = abs($from - $to); $suffix = (($from > $to) ? ("from now") : ("ago")); foreach($units as $unit => $mult) if($diff >= $mult) { $and = (($mult != 1) ? ("") : ("and ")); $output .= ", ".$and.intval($diff / $mult)." ".$unit.((intval($diff / $mult) == 1) ? ("") : ("s")); $diff -= intval($diff / $mult) * $mult; } $output .= " ".$suffix; $output = substr($output, strlen(", ")); return $output; } ?> ======================= Basically, if you type <?php echo rel_time("March 12, 2011 7:00 PM"); ?>, it will show you the time ago relative to the current time. But there's two problems. 1) The time it sends out is about 5hrs early (the actual time is 7:00pm, I set the rel time to 7:00pm, but the time it displays reads '5 hours ago, 1 minute, and 3 seconds ago'. I'm not much of a coder, but judging by the looks of it, it would appear correct... but apparently not. 2) My second gripe is that the code shows too many increments of date. What I mean is, if if I set the date to over a year ago, it would display the years,months,weeks,days,minutes,seconds. That is way too much increments. I just want it to display seconds, if I submitted it seconds ago, just display minutes if it was displayed minutes ago, and display days if it was submitted days ago. You get the idea. Friends, family, fellow coders, and bored people- can you help a nooblet? Thanks! I found the code below which checks to make sure something the user entered into a text field is an actual URL. I am looking to confirm that something a user enters is an actual link to an IMAGE, so does anyone know how I could adjust this code below to do that? Basically, this code below would accept http://monkeys.com AND http://monkeys.com/images/monkey.jpg. I want to alter the code so that http://monkeys.com would NOT be accepted since it's not an image. Essentially, I want to make sure whatever the user enters ends with .jpg, .gif or .png. Anyone know how to do this?
