A quick question:
what function is used to remove an array element from an array? Like
array_pop(), except one by which I can refer to the element by its
associative index rather than just the last element of the array.
For more detail with what I'm doing, I have two versions of a <select>
listbox -- one that includes an <option> with selected="yes" (if the
user is calling this page from submitting a form). The other version is
for users who are NOT calling this page from submitting a form, i.e. for
the first time.
I would like, in the first version (if ($formfilled)), to REMOVE the
element $temprow['div_name'] from the array $temprow so that it doesn't
appear a second time (in the WHILE loop), since it has already been
echoed above the WHILE loop.
Is this even possible?
$home_div_id = $myrow['home_div_id']; // (from another SQL query
$div_name = $myrow['div_name']; // earlier in the script)
$tempsql = "SELECT divisions.div_name, divisions.div_id
FROM divisions";
$tempresult = mysql_query($tempsql, $db);
$temprow = mysql_fetch_array($tempresult);
if ($formfilled) { // if this page is called with
// the form fields filled, grab
// $home_div_id and make it
// selected="yes"
echo "<select name=\"home_div_id\">\n";
echo "<option value=\"$home_div_id\"
selected=\"yes\">$div_name</option>\n";
while ($temprow = mysql_fetch_array($tempresult)) {
echo "<option value=\"" . $temprow['div_id']
. "\">" . $temprow['div_name'] . "</option>\n";
}
echo "</select>\n";
} else { // if this page is called with
// blank form fields, same thing
// except no "selected" attribute
echo "<select name=\"home_div_id\">\n";
while ($temprow = mysql_fetch_array($tempresult)) {
echo "<option value=\"" . $temprow['div_id']
. "\">" . $temprow['div_name'] . "</option>\n";
}
echo "</select>\n";
}
