Bitte helfen Sie mir bezüglich des im Titel angegebenen Problems.Warum die MySQL-Abfrage in PHP nicht funktioniert?
Eingabeformular Seitencode:
<?
db_connect();
$query1 = "SELECT *, DATE_FORMAT(eventdate,'%m/%d/%y') AS
eventdate,DATE_FORMAT(throughdate,'%m/%d/%y') AS throughdate FROM events WHERE id = " . mysql_real_escape_string($_REQUEST['id']);
$result1 = mysql_query($query1) or die("Error - query failed " . mysql_error());
if (mysql_num_rows($result1) == 0) {
print "<p>Error - no such event.</p>\n";
return;
}
else {
$qry_event1 = mysql_fetch_array($result1);
}
// default the formaction to the query
if (! isset($_REQUEST['formaction'])) { $_REQUEST['formaction'] = 'query'; }
?>
<form name="eventform" method="post" action="act_updevent.php">
<input type="hidden" name="submit_check" value="1">
<input type="hidden" name="formaction" value="form">
<!-- if we are editing, $id will exist. Pass it along. -->
<input type="hidden" name="id" value="<?php $qry_event1['id'];?>">

Was ich nach dem Drucken der Abfrage sehen kann, ist, dass es nicht den Wert von id bekommt aber alle Felder aus der Form aber warum?
könnte ich vorschlagen, um vorbereitete Aussagen zu verwenden? –
Bitte geben Sie mir einen nützlichen Vorschlag, um das Problem zu lösen. – rock
