variabele vergelijken met tabel entry
ik probeer dus momenteel een soort film bibliotheek te maken wat aardig lukt maar nu probeer ik een eerder gedefinieerde variabele te vergelijken met een database invulling maar krijg dus de foutmelding:
Warning: mysql_num_rows(): supplied argument is not a valid MySQL result resource in ... on line 461
No Files Found.
mocht iemand me kunnen helpen, bedankt op voorhand!

- verwijder de backticks
- haal de variabele buiten de quotes
- gebruik quotes voor tekstuele array-sleutels
dan wordt het
Code (php)
1
$result = mysql_query("SELECT * FROM files WHERE url='".$row['imdb']."'");
Code (php)
1
<?php ?>
Dit is regel 461:
- gebruik

- gebruik geen * maar selecteer wat je wil hebben: bijvoorbeeld: id, gebruikersnaam, email

voeg dan ook even mysql_error(); toe, de weet je de exacte fout
