Redigering/sletning af data i MySQL database
Hej.Jeg kunne godt tænke mig at vide om det er muligt at redigerer eller slette den data man har i en MySQl Databse via en php komando.
Hvis man nu skulle ændre eller slette/redigerer et link fra en linkoversikt som denne, hvad kan man så gøre?
Min kode ser således ud:
#add.php
<html><head></head><body>
<p align="center">
<table border="0" cellpadding="0" cellspacing="0" style="border-collapse: collapse" bordercolor="#111111" width="100%" id="AutoNumber1">
<tr>
<td bgcolor="#656565" width="100%" colspan="3"><p align="center"><b><font color="#ffffff">Tilføj Link</font></b></p></td>
</tr>
<tr>
<td width="3%"></td>
<td width="94%">
<br>
<p align="center">
<table border="0" cellpadding="0" cellspacing="0" style="border-collapse: collapse" bordercolor="#111111" id="AutoNumber1">
<form action="index.php?pageid=7" method="post">

</form>
