Linking data within MySQL tables into 1 table with PHP Code - php

Question

Background info:
I am trying to create a digital job raising system. Admin raises a job sheet and pulls in a client from "tblclient" table, fills out the details of the job and then assigns the job sheet to a employee user.
With this being said I am having difficulty pulling data from the clients table and users table then linking them to a row in the jobs table. I am new to PHP coding and am unsure how to script it out so my user can select the client and all the client details are attached to the job sheet and then coding it so the job sheet can be moved around between users.
This is so that when the job is complete the Admin can preview the job sheet with all the client details on it, job details and print with all the information on screen.
Is there any tutorials I can use for this procedure?
Notes:
I currently have a form that will insert the job data into the job table, I just don't know what code to use to pull in users/clients and link it to that specific job.
Thanks

ahh yes, I understand what this code is doing but not familiar with the syntax. I got an error:
Parse error: syntax error, unexpected ';' in...
I think you left out an ")" but even after reinstating it, my dropdown menu isn't populated:
<select name='clientid'>
<?php
$query="SELECT * FROM tblclients";
$result=mysql_query($query) or die(mysql_error());
while($row=mysql_fetch_assoc($result)){
echo "<option value='".$row['Client_ID']."'>".stripslashes($row['ClientName']." </option>";
}
?>
`

Answer 1

When inputting your job, you will want a field in your form containing clientid and another containing userid. The following is an example of how that might be done.
<select name='clientid'>
<?php
$query="SELECT * FROM ClientTable";
$result=mysql_query($query) or die(mysql_error());
while($row=mysql_fetch_assoc($result)){
echo "<option value='".$row['ClientID']."'>".stripslashes($row['ClientName']."</option>";
}
?>
</select>
Then when you want to output the job with all it's information, when you run the query you should use the LEFT JOIN command, for example
$query="SELECT * FROM JobTable
LEFT JOIN UserTable ON UserTable.UserID=JobTable.UserID
LEFT JOIN ClientTable ON ClientTable.ClientID=JobTable.ClientID
WHERE JobID='".mysql_real_escape_string($jobid)."'";
$result=mysql_query($query) or die(mysql_error());
That grabs the appropriate client and user informations by their IDs (which I hope you've set up with auto-increment by the way)
