PHP - Trouble Getting All Results From Query Array

If I have a db with these fields: displayname, title

and I run a successful query on the db, will this code:


if (mysql_num_rows($results) == 0) {
         return "!fail";
      } else {
         while ($row = mysql_fetch_assoc($results)) {
             extract($row);
         }
         
         return $row;
      }


 create an associative array of $var = array(array('displayname' => value, 'title' => value), array('displayname' => value, 'title' => value)...)

If not, is there a way to do so, especially when I will not know the names or number of fields in a db table?

Hi All,

First time posting here. I've googled the problem, but can't seem to find a response that's the same.

All I want to do is have a list of id numbers and for each id number in the array, submit a MySQL query to retrieve information relating to the id number.

When I execute the code below however, I end up with only the last item in the array being printed in the echo statement.

Any clues?

Thanks,

Code: [Select]
// get array of ids
$ids = getIDs($ids);

// loop through input list
foreach ($ids as &$id) {
getVarDetails($id);
}

function getVarDetails($local)
{
$con = mysql_connect('localhost:3306', 'root', '********');
if (!$con)
{
die('Could not connect: ' . mysql_error());
}

// set database as Ensembl
mysql_select_db("Ensembl", $con);

$result = mysql_query("SELECT * FROM variations WHERE name = '$local' LIMIT 1");
$row = mysql_fetch_array($result)

while($row = mysql_fetch_array($result))
{
echo $row['name'] . " " . $row['id'];
echo "<br />";
}

// close connection
mysql_close($con);
}

Hello all,   Based on the suggestion of you wonderful folks here, I went away for a few days (to learn about PDO and Prepared Statements) in order to replace the MySQLi commands in my code. That's gone pretty well thus far...with me having learnt and successfully replaced most of my "bad" code with elegant, SQL-Injection-proof code (or so I hope).   The one-and-only problem I'm having (for now at least) is that I'm having trouble understanding how to execute an UPDATE query within the resultset of a SELECT query (using PDO and prepared statements, of course).   Let me explain (my scenario), and since a picture speaks a thousand words I've also inlcuded a screenshot to show you guys my setup:   In my table I have two columns (which are essentially flags i.e. Y/N), one for "items alreay purchased" and the other for "items to be purchased later". The first flag, if/when set ON (Y) will highlight row(s) in red...and the second flag will highlight row(s) in blue (when set ON).   I initially had four buttons, two each for setting the flags/columns to "Y", and another two to reverse the columns/flags to "N". That was when I had my delete functionality as a separate operation on a separate tab/list item, and that was fine.   Now that I've realized I can include both operations (update and delete) on just the one tab, I've also figured it would be better to pare down those four buttons (into just two), and set them up as a toggle feature i.e. if the value is currently "Y" then the button will set it to "N", and vice versa.   So, looking at my attached picture, if a person selects (using the checkboxes) the first four rows and clicks the first button (labeled "Toggle selected items as Purchased/Not Purchased") then the following must happen:   1. The purchased_flag for rows # 2 and 4 must be switched OFF (set to N)...so they will no longer be highlighted in red. 2. The purchased_flag for row # 3 must be switched ON (set to Y)...so that row will now be highlighted in red. 3. Nothing must be done to rows # 1 and 5 since: a) row 5 was not selected/checked to begin with, and b) row # 1 has its purchase_later_flag set ON (to Y), so it must be skipped over.   Looking at my code below, I'm guessing (and here's where I need the help) that there's something wrong in the code within the section that says "/*** loop through the results/collection of checked items ***/". I've probably made it more complex than it should be, and that's due to the fact that I have no idea what I'm doing (or rather, how I should be doing it), and this has driven me insane for the last 2 days...which prompted me to "throw in the towel" and seek the help of you very helpful and intellegent folks. BTW, I am a newbie at this, so if I could be provided the exact code, that would be most wonderful, and much highly appreciated.   Thanks to you folks, I'm feeling real good (with a great sense of achievement) after having come here and got the great advice to learn PDO and prepared statements.   Just this one nasty little hurdle is stopping me from getting to "end-of-job" on my very first WebApp. BTW, sorry about the long post...this is the best/only way I could clearly explaing my situation.   Cheers guys!

case "update-delete":
	if(isset($_POST['highlight-purchased'])) 
		{
			// ****** Setup customized query to obtain only items that are checked ******
			$sql = "SELECT * FROM shoplist WHERE";
					for($i=0; $i < count($_POST['checkboxes']); $i++)
						{
							$sql=$sql . " idnumber=" . $_POST['checkboxes'][$i] . " or";
						}
					$sql= rtrim($sql, "or");
											
			$statement = $conn->prepare($sql);
			$statement->execute();
																						
			// *** fetch results for all checked items (1st query) *** //
			$result = $statement->fetchAll();

			$statement->closeCursor();
											
			// Setup query that will change the purchased flag to "N", if it's currently set to "Y"
			$sqlSetToN = "UPDATE shoplist SET purchased = 'N' WHERE purchased = 'Y'";
											
			// Setup query that will change the purchased flag to "Y", if it's currently set to "N", "", or NULL
			$sqlSetToY = "UPDATE shoplist SET purchased = 'Y' WHERE purchased = 'N' OR purchased = '' OR purchased IS NULL";

			$statementSetToN = $conn->prepare($sqlSetToN);
			$statementSetToY = $conn->prepare($sqlSetToY);
											
			/*** loop through the results/collection of checked items ***/
			foreach($result as $row)
				{
					if ($row["purchased"] != "Y")
						{
							// *** fetch one row at a time pertaining to the 2nd query *** //
							$resultSetToY = $statementSetToY->fetch();
															
							foreach($resultSetToY as $row)
								{															
									$statementSetToY->execute();																
								}
						}
					else
						{
							// *** fetch one row at a time pertaining to the 2nd query *** //
							$resultSetToN = $statementSetToN->fetch();
															
							foreach($resultSetToN as $row)
								{															
									$statementSetToN->execute();																
								}
						}
				}
				break;

What would be the correct way to close a mysql query?

At current the second query below returns results from the 1st query AND the 2nd query
The 3rd query returns results from the 1st, 2nd and 3rd query.
 etc etc.

At the moment I get somthing returned along the lines of...

Hey Everybody,

I am writing a SUPER SIMPLE script and for some reason I cannot figure this issue out. I guess I'm too close to the situation and have spent too many hours staring at this script.

Here's the problem: I am running a basic SQL query through php that should return multiple rows of data and instead returns the first row multiple times.

I'm not sure what the problem is, but I'm sure YOU can help!


<?php

  //Get Invoice Rows
  $sql = 'SELECT * FROM timecard WHERE INVOICE_ID=\'1000\'';
  $result = mysql_query($sql);
  $rows = mysql_fetch_array($result);
  $num = mysql_num_rows($result);

  //Build Current Invoice
  $i=0;
  $invoice = '<table class="invoice" cellspacing="0" cellpadding="0">';                   
  $invoice .= '<tr class="heading"><td>#</td><td>Invoice</td><td>Date</td><td>Time In</td><td>Time Out</td><td>Hours</td><td>$/Hr</td><td>Sub Total</td></tr>';
  while($i < $num){
    if( $i%2 )
    {
      $eo = 'odd';
    }
    else
    {
      $eo = 'even';
    }
    $invoice .= '<tr id="invoiceRow" class="'.$eo.'"><td>'.$rows[0].'</td><td>PHG'.$rows[1].'</td><td>'.$rows[2].', '.$rows[4].' '.$rows[3].', '.$rows[5].'</td><td>'.$rows[6].'</td><td>'.$rows[7].'</td><td>'.$rows[8].'</td><td>'.$rows[9].'</td><td>'.$rows[10].'</td></tr>';
    $runningTotal[$i] = $rows[10];
    $i++;
  }
  //Get Total
  $total = array_sum($runningTotal);
  $invoice .= '<tr><td colspan="7" style="background-color: #000000; color: #ffffff; font-weight: bold; padding-left: 5px;">Total</td><td align="right" style="background-color: #333333; font-weight: bold; color: #FFFFFF; padding-right: 5px;">'.$total.'</td>';
  $invoice .= '</table>';
  
  echo $invoice;

?>


Much thanks in advance for anyone that is able to resolve this problem, even just a try is nice!!

Thank You,

E
