I'm using the following in my php code:
$file="query.txt";
$f=fopen($file,'a');
fwrite($f,"Query String:".$_SERVER['QUERY_STRING']."\n");
fclose($f);
It never returns anything. I'm simply trying to record the queried url when someone visits (i.e. http://example.com/index.php?q=string. Other $_SERVER fields seem to work just fine, it only seems to be the query string that doesn't work. Maybe there's something I need to setup in my .htaccess?
I'm hoping someone has an answer to how to get this to information to show.
This solved the problem:
$_SERVER['REDIRECT_QUERY_STRING']

I've noticed a wierd behavior of php curl GET query to Cloudflare API https://api.cloudflare.com/client/v4/zones
When using Postman — everything is okay and it show correct response
But when trying to get via PHP it returns '1' for some reason. Here is my code and logs:
Also tried to pass in body, but it didn't work too
Please, help me to figure out the problem and fix it. Thanks!
p.s. i've also tried to pass urlencoded variable, but this also has no effect
The problem was in logs — i've just forgot to add second true parameter to print_r so it'll return the output
Calling $_GET['ip'] worked up until a recent wordpress update and now it's broken.
I don't know how Wordpress expects me to get the variable but the code I've been messing with and put together doesn't seem to work at all.
I'm clearly doing something wrong but I can't seem to wrap my head around making this work.
The code I'm trying to work with is here: https://pastebin.com/4iipisjU
UPDATE: The code works, the WPSupercache configuration file for nginx is what seems to have broken it.
You should be able to use get_query_var
<?php
$value = get_query_var( "paramA", "default value" );
?>
Also, $_GET['ip'] will refer to the query parameter IP that was passed as part of the request.
Is this actually what you are looking for? Or are you trying to see the IP of the client making the request? If the latter, this is incorrect.
Try change $get_ip_addr to:
$get_ip_addr = get_query_var('ip', $_GET['ip']);
I have an issue with post variables in Codeigniter, for now I fixed it, but I'm not sure if this is fine, in other words, I'd really like to know why I had issue only on hosting server, not on local.
The problem:
I wanted more secure script so I replaced $_POST/$_GET with $this->input->post and $this->input->get, like in this example:
if(!empty($this->input->get('endDate'))){
$data['datepicker'] = $this->input->get('thisDate');
}
this was all working fine on my localhost, but I assume it is wrong way, as when I deployed to the hosting server, I've got ajax parse error from validation engine that I'm using, I couldn't log in the system, getting all the time ajax parse error, and somehow figured out that whenever I checked if empty$this->input->post('var) or the same with get, was wrong.
I have checked the input class from Codeigniter and figured out, that $this->input->post is returning true/false, so I changed the scripts in the format like this:
if(!($this->input->get('endDate'))){
$data['datepicker'] = $this->input->get('thisDate');
}
this worked fine.
I'm still wondering - why the code worked on the localhost, but it didn't on the server or what is the best way to check if the POST/GET variable is empty or not.Seems I really miss something out.
Thank you.
Consider that checking for empty($this->post->get('var')) will always return false, no matter if the POST/GET exists, so it might be for that reason only. - So i'm not sure why you got the error on a different environment, but the first statement is wrong, it's exactly like writing if(true)
Also, I'd check for a strong assertion of false for inputs, You never know when you might need a zero as an input and if you're used to this practice, you might get an accidental false.
i am creating a CMS and have php creating a page. i have a while loop like this
while($row = mysql_fetch_array($results)) {
echo "some html code" . $row['name'];
its shortend but hopefully you get the point. i have the full thing in my page working just as it should and i wanted to move it to a function include as i want to reuse it. the problem is i do that and it stops working.
i did some testing and found that the function is getting the query result and after doing a var dump both were identical the problem comes when i try to assign it to an array. it comes back as false so in the above code, for example,
$row = false;
im toatly lost in this and if my explanation is confusing i appologise but i am a bit of a newbie i have tried searching but....i dont really know where to begin
any thoughts.
the query you are doing is basically wrong, try posting exactly the code which you have in $query and then let us see the problem.
also, it is better to use mysqli functions.
but for this, edit the question and type the query, or simply put a die(mysql_error()) at the end of your query which is in $query. It will show your exact error.
i fugured it out
when i was testing the function i commented out the original code on the main page but for some reason i had not comented out enough (it was a mix of php and html clearly the php had not been commented out properly) this must have been causing a clash of some kind as when i put the function above the code on my page the function worked and the long code below it did not
sorry for wasting your time guys
I'm working with a very simple mock-up application to query a DB and display the results on a map. The application sends a GET httprequest to a server which returns a serialized array of value. The basic structure of the httprequest is:
httpRequest.open("GET","handle-query.php?query=" + queryJs)
and, on the other side:
$queryPhp = $_GET["query"];
When the query looks like this...
["SELECT%SUM(commit)%FROM%financialdata%WHERE%region='Centre'", "SELECT%SUM(commit)%FROM%financialdata%WHERE%region='Kara'", "SELECT%SUM(commit)%FROM%financialdata%WHERE%region='Maritime'", "SELECT%SUM(commit)%FROM%financialdata%WHERE%region='Plateaux'", "SELECT%SUM(commit)%FROM%financialdata%WHERE%region='Savanes'"]
...then it is passed to the server properly, and generates a response. However, when the query looks like this...
["SELECT%SUM(commit)%FROM%financialdata%WHERE%prefect='Sotouboua'", "SELECT%SUM(commit)%FROM%financialdata%WHERE%prefect='Tchamba'", "SELECT%SUM(commit)%FROM%financialdata%WHERE%prefect='Tchaoudjo'", "SELECT%SUM(commit)%FROM%financialdata%WHERE%prefect='Assoli'", "SELECT%SUM(commit)%FROM%financialdata%WHERE%prefect='Bassar'", "SELECT%SUM(commit)%FROM%financialdata%WHERE%prefect='Bimah'", "SELECT%SUM(commit)%FROM%financialdata%WHERE%prefect='Doufelgou'", "SELECT%SUM(commit)%FROM%financialdata%WHERE%prefect='Keran'", "SELECT%SUM(commit)%FROM%financialdata%WHERE%prefect='Kozah'", "SELECT%SUM(commit)%FROM%financialdata%WHERE%prefect='Golfe'", "SELECT%SUM(commit)%FROM%financialdata%WHERE%prefect='Lacs'", "SELECT%SUM(commit)%FROM%financialdata%WHERE%prefect='Vo'", "SELECT%SUM(commit)%FROM%financialdata%WHERE%prefect='Yoto'", "SELECT%SUM(commit)%FROM%financialdata%WHERE%prefect='Zio'", "SELECT%SUM(commit)%FROM%financialdata%WHERE%prefect='Amou'", "SELECT%SUM(commit)%FROM%financialdata%WHERE%prefect='Haho'", "SELECT%SUM(commit)%FROM%financialdata%WHERE%prefect='Kloto'", "SELECT%SUM(commit)%FROM%financialdata%WHERE%prefect='Ogou'", "SELECT%SUM(commit)%FROM%financialdata%WHERE%prefect='Wawa'", "SELECT%SUM(commit)%FROM%financialdata%WHERE%prefect='Oti'", "SELECT%SUM(commit)%FROM%financialdata%WHERE%prefect='Tone'"]
...then the server receives an empty string. Both of the strings are generated by the same function, and both work perfectly on my virtual server (WAMP). If anyone has any ideas it would be greatly appreciated.
(P.S. After reading I realize that I should be using a framework with better sanitization, etc., but this is just a demo that will need to live online for maybe 2 hours, and it would be better to fix this small thing than start over. It works perfectly on my localhost.)
To actually answer your question, you're sending a get parameter as query (handle-query.php?query=) and then pulling it off as queryJS (queryJs).
$_GET['query'] // instead of $_GET['queryJs']
should do it.
(And as everyone has pointed out, don't send SQL in the clear or otherwise over the wire, unless you plan on not actually executing the SQL, and you just like to advertise your db structure, maybe it is that pretty.)
