PHP - Pagination For A Single Record

I'm trying to update records in a Db. I have a record called "classOffering" and I have associated records for that offering called "classSessions". You have 1 classOffering for 1 to 6 classSessions. The process I use has the user create the classOffering and say how many classSession there will be then I create how ever many sessions they say. I then display the classSessions so they can be edited and updated in the Db. I can't seem to update and set more than one record even though there are more.
I know I need to use a while or foreach statement, but I can't seem to do it.
Here's my code so far:

$sessSet = "UPDATE classSessions
                   SET startDate= '$startDate', startTime= '$startTime', time= '$time'
                   WHERE classSessions.sessionId = $sessionId
                   ";


Thanks for any help.

Is it no problem to give the SUM of integers in a column, but is it also possible to give the SUM of integers in a record (automatically)?

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.

Hi Guys,

I appreciate your help! What I am doing is making a Choose Your Own Adventure Game and what I would like to do is the following.

Record the moves of the person Put those moves on a page telling them their - say - 5 latest games Record the time it took them to complete the adventure Record that in a High Score database
I know that I will need to employ the use of MYSQL databases and PHP, but I'm a total noob! Any help would be greatly appreciated!

Code: [Select]
$sql = "SELECT poster_id from phpbb_posts WHERE topic_id = ".$topic_id." ";
$result = $db->sql_query($sql); //same as mysql_query
$row = $db->sql_fetchrow($result); // same as mysql_fetch array.
var_dump($row);

With this code (i commented the query function for you) im getting
Code: [Select]
array
  'poster_id' => string '59' (length=2)
When I run this into SQL in phpmyadmin I'm getting
Code: [Select]
59 56 //this is what I want

I need to get all of the records, not just the first one. I have even tried using replacing the function with mysql_query and mysql_fetch_array
any ideas? It's a bit late, so I may just be making a simple mistake.  Thanks!

Hey,
I'm trying to check if a username is unique, but for some reason none of the methods that I've looked up seem to work.

I'm aiming for the code to check if a username is unique, and if get the user to input the name again.

$get = "SELECT `i` FROM `m` WHERE `i`=\"$r\"";
$checkResults = mysql_query($getRandomness);
while(mysql_num_row($checkResults) > 0)
{
  //some code...
  //check again

$get = "SELECT `i` FROM `m` WHERE `i`=$r";

$checkResults = mysql_query($get);
}


The error comes from the while line, but it comes up during the first check because the record is empty.
This is the error:
"Fatal error: Call to undefined function mysql_num_row()"

I'm having an issue updating a records. 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!

Please help me

I currently have a list of host addresses. I need to get the mx records for them.

I was looking at the documentation, and found the getmxrr(). Would that send back the mx record, or just true if it has one?

New to php so I'm having trouble with deleting a record from my php table.


This is my code for my page where the records are being displayed. I have a delete statement that is not working properly. Also, I was thinking maybe I need a array to delete records? Please help!

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

Hey Guys,

Im slowly updating our website to php/mysql, im getting there slowly but stuck at the minute. Im try to create a form where we can edit one of the pages text and then update the text in the database if that makes sense 

Basically at the moment i have a form where you can see the pages text like so:

<table width="400" border="0" align="center" cellpadding="3" cellspacing="1">
<tr>
<td><strong>Edit About Us English </strong></td>
</tr>
</table>

<table width="400" border="0" align="center" cellpadding="0" cellspacing="1">
<tr>
<td><form name="form1" method="post" action="send_update_english.php">
<table width="100%" border="0" cellspacing="1" cellpadding="3">

<tr>
<td>Detail</td>
<td>:</td>
<td><textarea name="detail" cols="50" rows="4" id="detail">

[b]<?php

mysql_connect("localhost", "web148", "123") or die(mysql_error());
mysql_select_db("web148") or die(mysql_error());

mysql_query("SET names 'utf8'");

$result = mysql_query("SELECT body FROM aboutenglish WHERE ID = '1'");


$row = mysql_fetch_array( $result );

echo nl2br($row['body']);


?>[/b]

</textarea></td>
</tr>
<tr>
<td>&nbsp;</td>
<td>&nbsp;</td>
<td><input type="submit" name="Submit" value="Submit"> <input type="reset" name="Submit2" value="Reset"></td>
</tr>
</table>
</form>
</td>
</tr>
</table>

Ive got that php bit in the middle to pull out the text thats on that page but not sure if thats correct or not. But anyways on the 'send form' page i have:

<?php

// Details
[b]$message="$detail";[/b]

mysql_connect("localhost", "web148", "123") or die(mysql_error());
mysql_select_db("web148") or die(mysql_error());

mysql_query("SET names 'utf8'");
$result = mysql_query("UPDATE aboutenglish SET body = '$message' where ID = '1'");


?>


the update query works if i put text in there, but when i use '$message' the database is left blank.


This is only my second week doing all this stuff, so bare with me 

I appreciate your answers.

        }
    }
} else {
    echo "Invalid file";
}
?>

File is uploaded in upload folder correctly. What's wrong with prepare and execute statement? What can be the reason not inserting record? What's the way to debug php pdo query?
