Alright, wasn't quite sure how to summarize this in the title, but I want to:

Check if a user status is "active" or not based on the UserName input.

I have a table witch holds:

Code: [Select]
VarChar Username Var CharPassWord int Active
Ted TedsPW 1
something like the above(assuming it formatted correctly.

In my php script I will want to input a variable for Username to check for:

inputUN in this example would be "Ted".

$UserNameToCheck = $_GET['inputUN'];

Then I want to check for that UserName in the database, if it exists, I want pull the value for the "Active" field for just that UserName and echo it.

Thanks for any help.

I am using php to upload a file to my server, and at the same time inserting the files name and url into my mysql database.

$sql = "UPDATE uploads SET name = '$name', url='$target_path'";
    $statement = $dbh->prepare($sql); 
    $statement->execute();

Hello coders,

I'm using this code to grab random results from a table and it works well but I need it to be a non-repeating event.

Code: [Select]
$offset_result = mysql_query( " SELECT FLOOR(RAND() * COUNT(*)) AS `offset` FROM `jobs_board` ");
$offset_row = mysql_fetch_object( $offset_result );
$offset = $offset_row->offset;
I'm using this query followed by the html which is a set of divs with inline echo statements for the various variables I've localised from the table. Then I'm repeating that process a number of times to create a small list (I wanted to use a single while loop but cant figure it out at the moment). Anways, how can I make it so each query is random but also not repeated? At the moment they are indeed random but sometimes one same entry will appear a number of times consecutively...

Nice one guys, L-plate

Unique Form Entry To Mysql Db Situation

I spent several hours trying to figure this thing out. Thought I had it nailed, but still getting duplicate record entries into the MySQL DB when I do NOT want them. Here's the plot: People filling out the possible attendance form for a Ham Radio event *sometimes* bring a 2nd person (either a spouse or a friend). The 2nd person may, or may not, also has a Callsign which I need to put INSERT the same MySQL Callsign column. In any event, to also identify the 2nd person as coming 'with' the 1st person. MOST of the attendees are individuals with NO 2nd person. My entry form has these primary fields: callsign fullname AND... callsign2 fullname2 What I came up with was to process the MySQL INSERT for the primary callsign & fullname into their respective MySQL DB Columns (which works fine), and then........... immediately following the main Query INSERT, to do a substitution type thing depending on whether or not a form entry was made in the callsign2 field, AND/OR, the fullname2 field. This partially works, but if there is ONLY a primary callsign and fullname in the form, I'm still getting a duplicate record entry which includes the callsign in the `with` column (which should ONLY take place IF there is a 2nd person indicated). Confusing? Here is what I have been wrestling with to try and accomplish the objective, and now my eyes are glazed over ;-(


// TRICKY PART HERE

// If a 2nd Callsign AND a Fullname

if ($callsign2 != ' ' && $fullname2 != ' ') {

// Still make reference to the primary Callsign in the MySQL DB `with` column

$with = $callsign;

// Assignment to allow 2nd Callsign to be entered in the MySQL `callsign` column

$callsign=$callsign2;
$fullname=$fullname2;

$sql="INSERT INTO `mytable` (`callsign`, `fullname`, `with`)
VALUES ('$callsign', '$fullname', '$with')";

// If NO 2nd Callsign BUT a Fullname

} elseif ($callsign2 = ' ' && $fullname2 != ' ') {

// Make reference to the primary Callsign in the MySQL DB `with` column

$with = $callsign;

$callsign=$callsign2;
$fullname=$fullname2;

$sql="INSERT INTO `mytable` (`callsign`, `fullname`, `with`)
VALUES ('$callsign', '$fullname', '$with')";

} else {

// The only thing I could thing of to (hopefully) NOT make a 2nd entry 
// record in the MySQL DB IF there is NO 2nd person referenced

$with = $callsign;

}

if (!mysqli_query($con,$sql)) {
  die('Error: ' . mysqli_error($con));
}

I have a table that has pairs of matching records that are identified as matching on a specific column. In other words, 2 users submit data on the same record, and they are identified as matching and belonging to the same record data because the table column gameid is the same for the pair.

How can I output the information for the pair of matching records for each of these into a table repeating it until Ive looped through all records?

In other words I want to create 1 table with headers for each matching pair all the way down...

thanks in advance.

Not Detecting Duplicates

I've made a small chicken names website, and I also have a chicken name list as a thread on a chicken related forum. People submit their names, and I manually add them to the list. With the names growing so much, I decided to make a small background system that lets me put in the current list names, then the new names submitted. It will then run the lists, compare them, and spit out/ignore any duplicates and generate the new list.

But each time I use it, it doesn't get rid of the duplicates. Can anyone tell me why?

if($_GET['list_updater'] || $_POST['list_updater'])
{
if(!$_POST['current_list'] || !$_POST['new_names'])
{
?>
<table>
<form action="index.php" method="POST">
<input type="hidden" name="list_updater" value="1">
<tr>
<td>
<textarea name="current_list" cols="40" rows="20"></textarea>
</td>
</tr>

<tr>
<td>
<textarea name="new_names" cols="40" rows="20"></textarea>
</td>
</tr>
<tr>
<td><input type="submit" value="Generate New List"></td>
</tr>
</form>
</table>
<?php
}
else
{
//start our counting numbers
$x = 0;
$s = 0;
$a = 0;

//make our arrays
$check_to[0];
$new[0];

//get the values from our lists
$old_list = explode("\n",$_POST['current_list']);
$new_list = explode("\n",$_POST['new_names']);

//get new list variables
foreach($old_list as $value)
{
$check_to[$x] = $value;
$x++;
}

//add all our new names
foreach($new_list as $value)
{
for($s = 0; $s < count($new_list); $s++)
{

}
}
?>
<textarea cols="45" rows="20">
<?php
for($t = 0; $t < count($new); $t++)
{
echo $new[$t];
}
?>
</textarea>
