I have a MySQL database with 3 tables:
**articles:**
id - articletitle - articleorganization - articleurl - articledate
**tags:**
id - articletag
articles_tags
**id:**
article_id - tag_id
On my form I have text input boxes to fill in the information for Title, Organization, URL, and Date and I have checkboxes to capture Tag information.
This works very well but the problem comes when I need to edit an entry in the database. With that I have a similar form to the entry form but I can’t get the checkboxes to work. After some research and much help from Stackoverflow contributors, I’ve learned that what I need is a different type of database structure (which is what I now have, I originally only had 1 table, now I have the 3 listed above).
This leads me to redeveloping the entry form so now I am attempting to insert the Title, Organization, URL, and Date information into into the articles table and the Tag information into the tags table while also creating a relationship in the articles_tags table.
So far I’ve been unsuccessful in this attempt. Here is what I’ve been working with so far:
<?php
function renderForm($articletitle, $articleorganization, $articledate, $articleurl, $articletags )
{
?>

You are missing a keyword INTO in your SQL queries – INSERT INTO
mytable…You can also merge the last 2 tables into one – “tag_id, article_id, article_tags”.
And one advice – please read what PDO is and get rid of mysql_*.
