Putting it all together...displaying array!

Recommended Posts

Thanks to the great help from some great people on this message board I'm right at the finish line on this page.

 

I'm trying to mesh all the coding together at this point, and make it display the information. 

 

I keep getting 'mysql_fetch_assoc(): supplied argument is not a valid MySQL result resource....etc..(filename/location) on line 51.

 

Am I way off here???

<?php

        $db_host = 'localhost';
        $db_user = 'root';
        $db_pass = '';

        $db_in = new MySQLi ( $db_host, $db_user, $db_pass, 'sign_in' );
        $db_out = new MySQLi( $db_host, $db_user, $db_pass, 'sign_out' );

        if( $db_in->connect_error || $db_out->connect_error ) trigger_error( 'Unable to initiate database connections', E_USER_ERROR );

        $q_in =  'SELECT * FROM `customer sign-in`';
        $q_out = 'SELECT * FROM `customer sign-out`';

        if( ($r_in = $db_in->query($q_in)) === FALSE || ($r_out = $db_out->query($q_out)) === FALSE )
           trigger_error( 'Unable to grab ticket information from databases', E_USER_ERROR );

        $data_in = array(); $data_out = array();

        while( $row = $r_in->fetch_assoc() )
           $data_in[ $row['Ticket #'] ] = $row;
        $r_in->free();
           
        while( $row = $r_out->fetch_assoc() )
           $data_out[ $row['Ticket #'] ] = $row;
        $r_out->free();

        $result = array_diff_key( $data_in, $data_out );

           echo "<table border='1'>
        <tr>
        <th>ID</th>
        <th>Sign In Date</th>
        <th>RANK/CIV</th>
        <th>First Name</th>
        <th>Last Name</th>
        <th>Unit</th>
        <th>DSN/Roshan</th>
        <th>Classifications</th>
        <th>Services Requested</th>
        <th>Service Tag/ Serial Number</th>
        <th>Ticket #</th>
        <th>Make/ Model</th>
        </tr>";

    while($row = mysql_fetch_assoc($result)) {  // Retrieve data until no more
          {
          echo "<tr>";
          echo "<td>" . $row['ID'] . "</td>";
          echo "<td>" . $row['Sign in Date'] . "</td>";
          echo "<td>" . $row['Rank/CIV'] . "</td>";
          echo "<td>" . $row['First Name'] . "</td>";
          echo "<td>" . $row['Last Name'] . "</td>";
          echo "<td>" . $row['Unit'] . "</td>";
          echo "<td>" . $row['DSN/Roshan'] . "</td>";
          echo "<td>" . $row['Classifications'] . "</td>";
          echo "<td>" . $row['Services Requested'] . "</td>";
          echo "<td>" . $row['Service Tag/ Serial Number'] . "</td>";
          echo "<td>" . $row['Ticket #'] . "</td>";
          echo "<td>" . $row['Make/ Model'] . "</td>";
          echo "</tr>";
          }
        }
    ?>

You are using mysqli for your database functions.

 

You cannot use any of the mysql_ (non-i) statements. You would need to use the mysqli fetch_assoc method or function.

 

Edit: Also, why on earth do you have related data in two completely separate databases?

 

Ahhhh........the question everyone has asked me so far.

 

I do not own the data.....it's government owned and therefore I cannot change the way it's presented to me for review and presentation on the web page I'm trying to create.

 

All of this PHP is foreign to me in the end.....I spent many a hour on this message board to get to where I am now.....

 

The code below just does the array and returns the data in a web page that is very garbled.....if I could just change this to display the data in a 'table' on the page that would be ideal....unfortunately....with what I'm reading above.....I ummm.....feel dumber than I felt before I started this!

 

<?php 

$db_host = 'localhost';
$db_user = 'root';
$db_pass = '';

$db_in = new MySQLi ( $db_host, $db_user, $db_pass, 'sign_in' );
$db_out = new MySQLi( $db_host, $db_user, $db_pass, 'sign_out' );

if( $db_in->connect_error || $db_out->connect_error ) trigger_error( 'Unable to initiate database connections', E_USER_ERROR );

$q_in =  'SELECT * FROM `customer sign-in`';
$q_out = 'SELECT * FROM `customer sign-out`';

if( ($r_in = $db_in->query($q_in)) === FALSE || ($r_out = $db_out->query($q_out)) === FALSE )
trigger_error( 'Unable to grab ticket information from databases', E_USER_ERROR );

$data_in = array(); $data_out = array();

while( $row = $r_in->fetch_assoc() )
$data_in[ $row['Ticket #'] ] = $row;
$r_in->free();

while( $row = $r_out->fetch_assoc() )
$data_out[ $row['Ticket #'] ] = $row;
$r_out->free();

$result = array_diff_key( $data_in, $data_out );

print_r( $result );

?>

A) If you have a specific reason for using two databases (or any other conditions you are aware of that defines a problem you are asking someone to help you with), stating those at the START of a request for help or putting a comment in the code you are posting would be prudent.

 

B) If these two different databases are on the same database server and are accessible by the same database user, you can specify the database name and table (the format would be db_name.table_name instead of just table_name) in your queries and it's possible to write one query to do what you are trying to do.

C) Actually, since $result holds the result of the array_diff_key statement, there's no likely reason to re-retch any of the data from the either query (you have freed up the result resources, so they don't exist anyway.) If you use echo '<pre>',print_r($result,true),'</pre>'; to display what the sample data is and state what output you need from the data, someone can probably help.

I want to only display data on the web page if the equipment is listed in sign_in but not in sign_out based on the common field in both called "Ticket #".

 

^^^ Is that an accurate statement? That would imply someone signed something in that is currently not signed out? How would a Ticket # even exist in this case?

IF the two different databases have the same database user, the following query will get the records that have been signed in, but have not been signed out -

 

SELECT *
FROM sign_in.`customer sign-in` tin
WHERE NOT EXISTS (
SELECT *
FROM sign_out.`customer sign-out` tout
WHERE tin.`Ticket #` = tout.`Ticket #`
)

Per the poster who stated to run the code and then post what I'm getting as results, here is that!

 

This PHP page is loaded:

<?php 

$db_host = 'localhost';
$db_user = 'root';
$db_pass = '';

$db_in = new MySQLi ( $db_host, $db_user, $db_pass, 'sign_in' );
$db_out = new MySQLi( $db_host, $db_user, $db_pass, 'sign_out' );

if( $db_in->connect_error || $db_out->connect_error ) trigger_error( 'Unable to initiate database connections', E_USER_ERROR );

$q_in =  'SELECT * FROM `customer sign-in`';
$q_out = 'SELECT * FROM `customer sign-out`';

if( ($r_in = $db_in->query($q_in)) === FALSE || ($r_out = $db_out->query($q_out)) === FALSE )
trigger_error( 'Unable to grab ticket information from databases', E_USER_ERROR );

$data_in = array(); $data_out = array();

while( $row = $r_in->fetch_assoc() )
$data_in[ $row['Ticket #'] ] = $row;
$r_in->free();

while( $row = $r_out->fetch_assoc() )
$data_out[ $row['Ticket #'] ] = $row;
$r_out->free();

$result = array_diff_key( $data_in, $data_out );

print_r( $result );

?>

 

 

THIS is the result of 'print_r'

 

Array ([DODOIJSDF]=>Array([iD]=>617[sign in Date]=>2011-09-23 00:00:00[RANK/CIV]=>SPC/E4[First Name]=>Sean[Last Name]=>John[unit]=>510th[DSN/Roshan]=>0791110000[Classifications]=>NIPR[service Requested]=>Q-TIP Scan[service Tag/ Serial Number]=>DODOD[Ticket #]=>DODOIJSDF[MAKE/ Model]=>Dell E6500))

 

I need to find a way to format this data (which is the correct data, given the request of the code above....)....into a table for each record.

 

I've tried the numerous other ways that were posted here to get the results I need to get, yet none of them work with what I am trying to do.

This ended up being the final code....just in case anyone is ever looking for this type of thing again.
