I have a website that allows users to upload a picture, but I don't want any nudity in the photos. I found a scan written in php that I have succesfully implemented. The file and record are deleted if nudity is found to be in the file. I am just having trouble alerting the user as to why there pic wasn't kept. It just reloads the page. What could be the problem?
This code is the beginning of non commented code in my new2.php file:
if (isset($_GET['error'])) {
echo "Nudity found. Please try again with a more appropriate picture.";
sleep(5);
header("Location: new2.php");
}
This code is the code that scans the pic for nudity:
if($quant->isPorn()) {
$q = "delete from $table where id='$id'";
$result = mysql_query($q);
unlink("pics/".$picfile);
header('Location: new2.php?error=1');
} else {
header("Location: index.php?id=$id");
}
Any help would be greatly appreciated!
Your echo output won't be seen by the user. Output hasn't been sent to the browser yet, that happens at the end of your script. You redirect before that happens.
If you want to send a message, wait 5 seconds, and then redirect, do it client side.
<?php if (isset($_GET['error'])) { ?>
<p>Nudity found. Please try again with a more appropriate picture.</p>
<script>
setTimeout("self.location='new2.php'",5000);
</script>
<?php } ?>
Javascript is not needed. Just output the page containing your error, but change
sleep(5);
header("Location: new2.php");
to
header("Refresh: 5; url=new2.php");
This has the same effect as a <meta http-equiv="refresh">.
Don't do it from header. Use this instead:
<script> location="whatever.php?a=1"; </script>

your any participation would be very helpful.
after deleting that above code and i rewrite again to session not set but the same problem occuring like previous as after redirecting on https://localhost/sms/login.php the login page not opening and getting error like
enter image description here
updated is here below
code of session.php
enter image description here
code of session.php
enter image description here
code of adminDash.php
enter image description here
i want when we go on link like https://localhost/sms/admin/adminDash.php if there the session is to be not set then after it will redirect to https://localhost/sms/login.php
it say too many redirect, probably you are into a loop.
I have a website(www.website.com) and a mobile site (m.website.com) and I'm trying to allow users to "View Full Site" if they want from mobile. Currently I am using some Javascript to check screen width on full site then redirecting to mobile.
if (screen.width <= 699) {
document.location = "http://m.website.com";
}
This works fine. On the mobile site there is a "View Full Site" button. When you click this it redirects you to my script "force_desktop.php" which sets a cookie and then sends you to the main site.
<?php
setcookie("force_desktop", "1");
header("Location: http://www.mywebsite.com");
?>
Now that we set a cookie and redirected to the main website we need to check for the cookie instead of just checking for the screen width.
Logic
If Cookie force_desktop is found
Then exit
Else
run screen size test
Here is the code I attempted to use but doesn't work. This code is placed in my head.php file which will be run on every page and is placed between the script opening and closing tags.
Attempt 1
if($_COOKIE['force_desktop'] == '1' {
exit;
} else if($_COOKIE['force_desktop'] != '1' {
if (screen.width <= 699) {
document.location = "http://m.website.com";
}
};
Attempt 2
if(isset ($_COOKIE["force_desktop"])){
exit;
else
if (screen.width <= 699) {
document.location = "http://m.mywebsite.com";
};
Alternative logic that could work
IF Cookie force_desktop is not found AND screen.width <= 699
Then redirect to m.myseite.com
Else
Exit
Note
I have run the following script to make sure a cookie is being placed, and it is.
<?php
print_r($_COOKIE);
?>
I've run out of ideas and know my coding isn't correct, especially the If/Else statement within the If/Else statement. I also am not sure if it is better to use the "isset" to see if the cookie is being used or ($_COOKIES['variable'] == "#"). I'd really appreciate some good feedback on this one.
Thanks in advance for your help and suggestions,
Matt
You're mixing JavaScript and PHP. You're trying to use screen.width in your PHP script, which doesn't make sense. You need to use an echo statement to output the JavaScript into the page. It'll then check the user's screen resolution and do the redirect.
Try this:
if(isset ($_COOKIE["force_desktop"])){
exit;
}
else
{
echo '<script>
if (screen.width <= 699) {
document.location = "http://m.mywebsite.com";}
</script>';
};
you should do this test at the top of the php page, and for sure you cannot mix php and java script like this
u can alter this code like
<?php
$flag = 0;
if(isset($_COOKIE['force_desktop']))$flag++;
?>
later in the page use the code as soon as <head> tag starts
..
..
<head>
<?php
if(!$flag){
echo '<script>
if (screen.width <= 699) {
document.location = "http://m.mywebsite.com";
</script>';
}
?>
You cannot mix javascript and PHP, javascript is front end and PHP is back end. Try something like this:
if( $something ){
Header("Location: somewhere.php");
}
So i'm writing this code so that you either get forwarded to a certain page if you're the first one to hit the link, or you are sent back to the original page after being displayed a message if you're not what beginner mistake am i making?
<?php
$count = file_get_contents('counter.txt');
$count = trim($count);
if ($count="0")
{
$count = $count + 1;
$fl = fopen("counter.txt","w+");
fwrite($fl,$count);
fclose($fl);
header("Location: newpage.html");
}
else
{
fclose($fl);
echo "Sorry but the item has already been sold out";
header("Location: oldpage.html");
}
?>
As for the delay, you can accomplish it two different ways. The first is to use PHP header (like you are currently doing), but change it to look like this:
<?php
header("refresh:5;url=oldpage.html");
echo "Sorry but the item has already been sold out";
?>
The other way is to echo out a piece of HTML code, the meta-refresh:
<?php
echo '<meta http-equiv="refresh" content="2;url=oldpage.html">';
echo "Sorry but the item has already been sold out";
?>
In both examples, 5 is the amount of seconds until the refresh. Experiment with each one to see if it will fit your needs.
This might be some sort of syntax that I'm not familiar with, but none of my scripts have ever had the
<? code
I simply use
<?
Also since you did not delay our header tag the user will not see the previously echoed statement above it. It will automatically redirect before the page has time to output fully.
I have a page with links to reports. Whenever somebody clicks on one report, they can download the excel file. However, sometimes there are no fields to make a report; in that case, I want to display an alert message and after they click on "accept", they get redirected to the main panel. When they click on the report, they go to a controller that uses a switch to get the data. If there's no data, the model returns FALSE; so at the end of the controller, I check:
if ($result_array != FALSE)
to_excel($result_array->result_array(), $xls,$campos);
else {
echo "<script>alert('There are no fields to generate a report');</script>";
redirect('admin/ahm/panel');
}
If I get rid of redirect('admin/ahm/panel'); then the alert works, but it moves the user to the page that was supposed to generate the excel file. But if I use the redirect, the controller moves the user to the main panel without showing the alert.
echo "<script>
alert('There are no fields to generate a report');
window.location.href='admin/ahm/panel';
</script>";
and get rid of redirect line below.
You were mixing up two different worlds.
use this code to redirect the page
echo "<script>alert('There are no fields to generate a report');document.location='admin/ahm/panel'</script>";
Combining CodeIgniter and JavaScript:
//for using the base_url() function
$this->load->helper('url');
echo "<script type='javascript/text'>";
echo "alert('There are no fields to generate a report');"
echo "window.location.href = '" . base_url() . "admin/ahm/panel';"
echo "</script>";
Note: The redirect() function automatically includes the base_url path that is why it wasn't required there.
The redirect function cleans the output buffer and does a header('Location:...'); redirection and exits script execution. The part you are trying to echo will never be outputted.
You should either notify on the download page or notify on the page you redirect to about the missing data.
echo "<script>
window.location.href='admin/ahm/panel';
alert('There are no fields to generate a report');
</script>";
Try out this way it works...
First assign the window with the new page where the alert box must be displayed then show the alert box.
This way it works`
if ($result_array)
to_excel($result_array->result_array(), $xls,$campos);
else {
echo "<script>alert('There are no fields to generate a report');</script>";
echo "<script>redirect('admin/ahm/panel'); </script>";
}`
that worked but try it this way.
echo "<script>
alert('There are no fields to generate a report');
window.location.href='admin/ahm/panel';
</script>";
alert on top then location next
//functions.php:
<?php
function fx_alert_and_redirect($msg, $page){
**echo "<!DOCTYPE html><html><head>Login...</head><body><script type='text/javascript'>alert(\"" .$msg . "\");window.location.href=\"$page\";</script></body></html>";**
}
?>
//process_login-form.php:
<?php require_once '../app/utils/functions.php'; ?>
<?php
// ...
fx_alert_and_redirect("Mauvais nom d'usager ou mot de passe!", "../index.php?page=welcome");
?>
I was curious to know if i could do this, but found no examples on line
$info_find = mysql_query("SELECT info FROM sets WHERE category = '$selected_cat'")
or die( header ("location: index.php"));
Firstly doing it as above doesn't work. Can it be done?
Are there any drawbacks?
die() just writes its parameter out, it doesn't execute it. So a "or die()" construct will not help you there.
You can consider something like
or die(createRedirect("index.php"));
with
function createRedirect($where) {
$s='<html><head>';
$s.='<meta http-equiv="refresh" content="1; url='.$where.'">';
$s.='</head><body>If you are not automatically redirected click here';
$s.='</body></html>';
return $s;
}
if you are willing to accept the downsides of client-sided redirection
You can rewrite your code as
$info_find = mysql_query("SELECT info FROM sets WHERE category = '$selected_cat'") ;
if ($info_find === FALSE) {
header ('location: index.php');
die();
}
But, before use the header function, be sure you haven't send any output to the browser.
