    text
    copied!<p>I wish to update one table in my database, the data is from a php POST. (It is a page where multiple edits on rows can take place at once, then it processes them all at once after) and i want it so for each "row" or "loop", it builds a single query that can update all the rows at once.</p> <p>What i want to do, is in the query, select data from two other tables. E.g</p> <pre><code>Posted data: - Task = "Check current Sponsors" - User Assigned = "Dan" - Start Meeting = "Mar 1st" - Meetings Required = 2 </code></pre> <p>And for User Assigned, i want it to basically do this query:</p> <blockquote> <p>SELECT <code>id</code> FROM <code>team</code> WHERE <code>fullname</code> LIKE 'Dan'</p> </blockquote> <p>And for the start meeting, i want it to do this query:</p> <blockquote> <p>SELECT <code>id</code> FROM <code>meetings</code> WHERE <code>starttime</code>='".strtotime("Mar 1st")."'</p> </blockquote> <p>-- strtotime() makes a unix timestamp from a string.</p> <p>but i want it to do that for each "task" that gets submitted. (It is queued up via javascript and it sends them all into the same post request)</p> <p>Anyone have any ideas on how to do this? Thanks in advance</p> <p>Table Structures:</p> <p>Tasks:</p> <pre><code>id | startmid | length | task | uid | completed 1 | 2 | 1 | Check Sponsors | 1 | 0 </code></pre> <p>Meetings: (Joined by startmid)</p> <pre><code>id | maintask | starttime | endtime 1 | Sponsors | 1330007400 | 1330012800 </code></pre> <p>Team: (Joined by uid)</p> <pre><code>id | fullname | position | class | hidden 1 | Team | All Members | black | 0 2 | Dan S | Team Manager | green | 0 </code></pre>
