Hello,
I'm using DatabaseDeleteAction to delete rows from a table. But
before the row is deleted I would like to check it for a condition
(in this special case if the primary key of that row is not anymore
referenced in other tables - if it would be, than it can't be
deleted). How can I put this "checking" before the actual
"delete"-action will be executed?
I'm using a form for choosing the item to be deleted:
<xsl:template match="kpage">
<center>
<h3>Dokumenten-Kategorien</h3>
</center>
<form action="main.xsp" method="post">
<table class="list" align="center">
<xsl:apply-templates select="kategorie" />
<input type="hidden" name="id" value="{bid}" />
<input type="hidden" name="cocoon-action" value="Delete" />
<tr><td class="list" colspan="2"><input type="submit"
value="Loeschen" /></td></tr>
</table>
</form>
</xsl:template>
<xsl:template match="kategorie">
<tr>
<td class="list" width="300">
<xsl:value-of select="name" />
</td>
<td class="list">
<input type="radio" name="katid"
value="{normalize-space(id)}" />
</td>
</tr>
</xsl:template>
Regards
Jan
