MySQL row in een Query
Ik probeer een MySQL row in een INSERT query te stoppen, maar het gaat niet goed met de ' en de ", ik weet niet wanneer ik ze wel moet gebruiken en wanneer niet.
Stel voor ik heb deze query:
Code (php)
1
2
3
4
5

<?php
$result = mysql_query("SELECT * FROM Maps") or die(mysql_error());
$row = mysql_fetch_array( $result );
$row['Mapname'];
?>
$result = mysql_query("SELECT * FROM Maps") or die(mysql_error());
$row = mysql_fetch_array( $result );
$row['Mapname'];
?>
Hoe krijg ik dan: "Mapname" in een MySQL INSERT query. Kan iemand mij een voorbeeld geven?
"Parse error: syntax error, unexpected T_ENCAPSED_AND_WHITESPACE, expecting T_STRING or T_VARIABLE or T_NUM_STRING"

Dat zou kunnen, maar dat kost natuurlijk ook meer geheugen.

Oja, $member hoef je trouwens niet te escapen aangezien die variabel uit de database komt.

Ik weet niet of dit wel zo is.
En die $target, waar komt dat vandaan?

Zo heb je nog steeds alles in één en blijft het overzichtelijk.

Let wel, hier moet je wel zorgen dat je maar 1 rij uit je andere tabel krijgt. Er moet dus nog een WHERE clause zijn om de specifieke member_name uit die andere tabel te krijgen. Krijg je meerdere rijen terug, dan worden er dus ook meerdere geinsert.

Dat zou ik zo niet durven beweren, mysql_real_escape_string haalt de ' namelijk niet weg, maar zet er een \ voor. Deze is na het oslaan weer weg, en als je hem dus opvraagt heb je weer een normale string met een ' zonder \ ervoor.
