I'm using a form like this which runs from within a [query]... it always
works fine unless I try to update the table with an empty string.
============= BEGIN CODE ===============
[set mv_data_enable]1[/set]
[tag flag write]transactions[/tag]
<FORM METHOD=GET ACTION="[process]">
<input type=hidden name=mv_session_id value="[data session id]">
<INPUT TYPE=HIDDEN NAME="mv_data_table" VALUE="transactions">
<INPUT TYPE=HIDDEN NAME="mv_data_key" VALUE="order_number">
<INPUT TYPE=HIDDEN NAME="mv_data_function" VALUE="update">
<INPUT TYPE=HIDDEN NAME="mv_nextpage" VALUE="order_updated">
<INPUT TYPE=HIDDEN NAME="mv_data_fields" VALUE="notes">
<br>
<TEXTAREA NAME="notes">
[data table=transactions col=notes key=[loop-code]]
</TEXTAREA>
<INPUT TYPE=submit VALUE="Update & Unlock">
</FORM>
============= END CODE =================
I'll check the mysql logs as Racke wisely advised as well.
