PHP - Help With Print More Than One Selected Record

How to pull just I record of a column out of the 20 columns? This is not showing the results.

$SomeVar = 'pets';
$query =  "SELECT field1 FROM db1 WHERE id1 = '".$SomeVar."'";
$results=mysql_query($link);

echo $link;

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!

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!

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

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()"

        }
    }
} else {

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?

I have a "system" setup for posting some feedback questions on an internal website.
I have it setup to read a field "enabled" which has a 1 or 0. 0=disabled, 1=enabled
The script works if I manually change that field, ie it reads the correct question.
But need a way to have the questions listed then the one that needs to be shown on the site selected to be enabled on an admin page.
Something like a list with checkboxes or radio buttons?
How can I have one enabled and make sure the rest are not to prevent multiple questions being enabled?

I am creating a sticky topic feature for my forum and dont know how to keep
all topics marked sticky at the top of the list generated by the while loop. Any one have any ideas?
They are ordered by the post date column.

Here is the query:

$posts_info_query = $db->query("SELECT

p.post_subject,

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.

I am able to view record numbers 22, 84, and 203 by exectuing my PHP script with the correct record ID.

However, what I really want to do is have a simple form whereby I can input the desired record number and have it upload the data for me.

I imagine it would look something like this:
"SELECT * FROM mytable WHERE id = specified_record"

but need a bit of guidance to get the HTML input fields 'name' into the PHP request.

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!

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');

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!
