plaatje uit database
Quote:
En waarom wordt deze niet weergegeven? 9 van de 10x is het pad naar de juiste directory niet aanwezig.maar dan geeft ie het pllatje niet weer.
Maar duik eens in de html-broncode, daar kun je mogelijk een oplossing vinden.
mijn tabel is dit
tabel [cars]
velden
id
name
costs
speed
url (naar het plaatje)
alles wat in de tabel staat moet uitgevoerd worden naar html tabels.
dus zoiets als dit
Code (php)

mysql_query=("SELECT * FROM `[cars]`");
<tr><td>($cars->['id']</tr></td>
<tr><td>($cars->['name']</td></tr>
<tr><td>($cars->['costs']</td></tr> enzovoort
<tr><td>($cars->['id']</tr></td>
<tr><td>($cars->['name']</td></tr>
<tr><td>($cars->['costs']</td></tr> enzovoort
dit is mijn eerste script.

mysql_query("SELECT * FROM `[cars]`");
`[cars]` mag echt helemaal NOOIT als tabelnaam worden gebruikt! Gebruik gewoon cars en gooi die gore backtics en kansloze blokhaken dus weg. Verder is foutafhandeling de basis van ieder goed script en dat ontbreekt hier in zijn geheel.
Ik wens je veel succes met debuggen, in bovenstaand scriptje staan zeker 100 tot 200 fouten en problemen.
Ik zie dat hier gebruikt word gemaakt van mysql_close();
Is dit echt nodig? Of kan het ook zonder?
(sorry voor offtopic)
