REDIRECTING A PAGE IF A CONDITION ISN’T MET - Mar 31st, 2015
|
According to Dave Edis at Interactive Tools, if you wanted to redirect a page if there were no records in a table,
here’s how:
Just put this at the top of your page, after the get records call, and before any viewer code is output.
<?PHP
list($your_tableRecords, $your_tableMetaData) = getRecords(array(
'tableName' => your_table',
));
if (!$your_tableRecords) {
header("Location: http://www.example.com/newurl.php");
exit;
}
?>
If you want to change this to when a condition is met, take out the ! Which is the “not” operator in PHP.
And, if you wanted to redirect a page if there was only one record in the table, here's how you'd do that:
<?PHP
list($your_tableRecords, $your_tableMetaData) = getRecords(array(
'tableName' => your_table',
));
if($your_tableMetaData['totalRecords'] == 1)
{
header("Location: http://www.example.com/newurl.php");
exit;
}
?>
If you wanted to redirect if there was more than one record, just change the == 1 to > 1
______________________________________________
Expanding on this, if you want to redirect and pass one or more variables to the new page, try a variation of this.
In this case there are 2 variables;
group_code which is the value of a field in the portfolio_title_details table, and
noback which is a way to hide certain code on the new page
Right after the load records calls, insert the following code:
<?php if($portfolio_title_detailsMetaData['totalRecords'] == 1):?>
<?php foreach ($portfolio_title_detailsRecords as $record): ?>
<?php $group_code= $record['group_code'] ?>
<?php endforeach; ?>
<?php header("Location: http://www.your_domain.com/your_new_page.php?group_code=$group_code&no_back=1");
exit;
?>
Then on the new page, define the variables $group_code and $no_back
<?php $var1= $_REQUEST['group_code']; ?>
Use $var1 however you see fit.
and
<?php $var2= $_REQUEST['no_back']; ?>
<?php if (!$var2 == 1 ):?>
Your code to hide...
<?php endif ?>
