php table with hyperlink - record issue
I have two tables listed (on screen) in PHP and the left should be hyperlinked so when click on it the开发者_开发百科 right table will show a query. So at the beginning it should be empty then when clicked refresh the page with the selected listname's result.
unfortunately I have no experience with these things so i don't know the concept of it yet, but I am happy to learn:)
<form method="post" action="test.php">
<div id="left"><table>
<?php
$left="SELECT * FROM groups";
$resultleft=mysql_query($left);
while ($resultleft=mysql_query($left)) {
echo "<tr><td>".$left['id'].'</td><a href="???"><td>'.$left['listname']."</a></td></tr>";
}
?>
</table></div>
<div id="right"><table>
<?php
$right="SELECT * FROM grouplink WHERE grouplink.group_id= ";
$resultright=mysql_query($right);
while ($resultright=mysql_query($right)) {
echo "<tr><td>'.$right['people_name']."</td></tr>";
}
?>
</table></div>
<?php
if (isset($_POST('???'))){
echo "<meta http-equiv=\"refresh\" content=\"0;URL=test.php\">";
}
?>
</form>
any help would be appreciated
Can for example link to table.php?gid=n, where n would be the group id. You can then check if $_GET['gid'] isset, and if it is, take that id and put it in your query.
if(isset($_GET['gid']))
$right = sprintf("SELECT * FROM grouplink WHERE grouplink.group_id=%u", $_GET['gid']);
You need mysql_fetch_assoc
instead of mysql_query
in:
while ($resultleft=mysql_query($left)) {
echo "<tr><td>".$left['id'].'</td><a href="???"><td>'.$left['listname']."</a></td></tr>";
}
and also in:
$resultright=mysql_query($right);
while ($resultright=mysql_query($right)) {
echo "<tr><td>'.$right['people_name']."</td></tr>";
so this will be:
while ($left=mysql_fetch_assoc($resultleft)) {
echo "<tr><td>".$left['id'].'</td><a href="???"><td>'.$left['listname']."</a></td></tr>";
}
and similar issue with right
Thanks to Svish here is my new working code:
<?php include("db_con1.php");?>
<html>
<head>
</head>
<body>
<form method="post" action="test.php">
<div id="left">
<?php
$queryl = $pdo->prepare('SELECT id, name FROM test1 ORDER BY name ASC');
$queryl->execute();
?>
<ul>
<?php foreach ($queryl as $i => $rowl) { ?>
<li>
<?php if ($i)?>
<input name="checkbox_add[]" id="test_<?php echo $i ?>" type="checkbox" value="<? echo $rowl['id']; ?>"/>
<label for="test_<?php echo $i ?>"><a href="test1.php?gid=<?php echo $rowl['id']; ?>"><?php echo $rowl['name']; ?></a></label>
</li>
<?php } ?>
</ul>
</div>
<div id="right">
<?php
if(isset($_GET['gid'])) {
$gid=$_GET['gid'];
$queryr = $pdo->prepare('SELECT test3.name FROM test1, test2, test3 WHERE test1.id=test2.groupid AND test3.id=test2.peopleid AND test1.id='.$gid.' ORDER BY test3.name ASC');
$queryr->execute();
}
?>
<ul>
<?php foreach ($queryr as $i => $rowr) { ?>
<li>
<?php if ($i)?>
<input name="checkbox_del[]" id="test_<?php echo $i ?>" type="checkbox" value="<? echo $rowr['id']; ?>"/>
<label for="test_<?php echo $i ?>"><?php echo $rowr['name']; ?></label>
</li>
<?php } ?>
</ul>
</div>
</form>
</body>
