I think this is a tough one... and way above my head:
PLEASE READ ALL OF THE ABOVE TO UNDERSTAND WHAT I AM TRYING TO DO.
Having a bit of a rough time figuring out how to formulate php-mysql to insert
data into fields using a multiple dropdown box in a form.
to post I am using the following:
snip...
$categoriesIN = $_POST["categoriesIN"];
...snip...
<select name="$categoriesIN[]" multiple="multiple">
<OPTION>Choose Categories...</option>
<OPTION VALUE="<? echo $categoriesIN; ?>">1
<OPTION VALUE="<? echo $categoriesIN; ?>">2
<OPTION VALUE="<? echo $categoriesIN; ?>">3
<OPTION VALUE="<? echo $categoriesIN; ?>">4
<OPTION VALUE="<? echo $categoriesIN; ?>">5
</SELECT>
...snip...
$sql4 = "FOR ( $ii = 0 ; $ii < count($categoriesIN) ; $ii++ )
INSERT INTO temp (example) $categoriesIN[$ii]" ;
$result4 = mysql_query($sql4, $db);
...snip
this does not work! The other posts work like a charm... but this...
I cannot figure out what I should be entering where... I have tried several
different configurations, but nothing seems to work...
I found this as a model for entering the selections but can't figure out how to
modify it for my needs:
<select name="branch_no[]" multiple="multiple" size="5">
<option > Choose your location(s) </option>
<option value="3100">3100</option>
<option value="3105">3105</option>
<option value="3503"> 3503</option>
<option value="3504"> 3504</option>
</select>
What I would like to do is something like the following:
<select name="$categoriesIN[]" multiple="multiple">
<OPTION>Choose Categories...</option>
<OPTION VALUE="1">History
<OPTION VALUE="2">Temples
<OPTION VALUE="2">Pharaohs and Queens
<OPTION VALUE="4">Cleopatra
<OPTION VALUE="4">Mummies
</SELECT>
and going further, I would like to be able to use a table that actually holds
these values to feed them to the code above. I am sure this is possible but it
must take some huge knowledge and experience to do it.
BUT ...
as I look at things, I am wondering if the FOR statement in the above should be
used to do several INSERTs, that is, one $sql(number) per selected category...
now, would that require many $sqls or many INSERTs within the $sql ?
first, I think, $categoriesIN is string, but in the form you made it as
an array $categoriesIN[]. I think you have to "modify it a little bit,
something like {$categoriesIN}.'[]'
second, I think the php part "FOR ( $ii = 0 ; $ii < count($categoriesIN)
; $ii++ )" can't be part of the mysql statement, it should be "outside"
the statement
FOR ( $ii = 0 ; $ii < count($categoriesIN) ; $ii++ )
{
$sql4 = "INSERT INTO temp (example) $categoriesIN[$ii]" ;
$result4 = mysql_query($sql4, $db);
}
