我一直在设计一些网站。我一直在尝试使用多个 if(isset($_GET['type']) == 'page') { } 等等函数。他们似乎没有工作有人可以启发我吗?
<?php
if(isset($_GET['type']) == 'all') {
// View All Pages Title
echo '<h3>View All Pages</h3>';
if($control1 == 'all') {
echo '<table width="100%" border="0">';
echo '<tr>';
echo '<th scope="col">Page Name</th>';
echo '<th scope="col">Time Created</th>';
echo '<th scope="col">View</th>';
echo '<th scope="col">Edit</th>';
echo '<th scope="col">Delete</th>';
echo '</tr>';
$qry=mysql_query("SELECT * FROM page", $con);
if(!$qry) {
die("Query Failed: ". mysql_error());
}
while($row=mysql_fetch_array($qry)) {
echo '<tr>';
echo '<td height="38">'.$row['page_title'].'</td>';
echo '<td>'.$row['page_updated'].'</td>';
echo '<td><a href="page.php?view=page&page='.$row['page_link'].'">View</a></td>';
echo '<td><a href="page.php?edit='.$row['page_link'].'">Edit</td>';
echo '<td><a href="page.php?delete='.$row['id'].'">Delete</td>';
echo '</tr>';
}
echo '</table>';
}
else {
echo "<p>You can't view all the pages. Your Account does not hold the correct priorirty</p>";
}
}
elseif(isset($_GET['type']) == 'add') {
// Add New Page Title
echo '<h3>Add New Page</h3>';
if($control1 == 'all') {
echo '<p><a href="pages.php?type=add&add=control" target="new">Click Here to add a new page</a></p>';
}
else {
echo "<p>You can't add new pages. Your Account does not hold the correct priority.</p>";
}
}
elseif(isset($_GET['type']) == 'edit') {
// Edit Pages Title
echo '<h3>Edit a Page</h3>';
if($control1 == 'all') {
echo '<table width="100%" border="0">';
echo '<tr>';
echo '<th scope="col">Page Name</th>';
echo '<th scope="col">Edit</th>';
echo '</tr>';
$qry=mysql_query("SELECT * FROM page", $con);
if(!$qry) {
die("Query Failed: ". mysql_error());
}
while($row=mysql_fetch_array($qry)) {
echo '<tr>';
echo '<td height="38">'.$row['page_title'].'</td>';
echo '<td><a href="page.php?edit='.$row['page_link'].'">Edit</td>';
echo '</tr>';
}
echo '</table>';
}
else {
echo "<p>You can't edit any pages. Your Account does not hold the correct priority </p>";
}
}
?>
这是确切的代码。如果您能解释我可以做些什么来修复它,将不胜感激!提前致谢!
