I hope this helps you . I am having a little trouble with apache mod_rewrite, I need to be able to modify (append) a variable name to something else depending the regex in another variable in the URL: ,

code :

RewriteCond %{QUERY_STRING} shoes=(.*)\&awesome=(\b234(1|2)\d{4}\b)

https://localhost:85/fight?shoes=baby.firstlove&type=textype&awesome=23481234

RewriteCond %{QUERY_STRING} shoes=.+&awesome=(234[87]1234)
RewriteRule ^/?fight http://localhost:85/fight?shoes=baby.firstloveactual&subscriber=%1 [R,L]

mod_rewrite help to change Content-disposition based on URI

By : user1455520

I think the issue was by ths following , With mod_rewrite you can only change some specific header fields but to which the Content-Disposition header field doesn’t belong. You could only change the Content-Type header field:

code :

RewriteRule ^media/[^/]+\.mp3$ - [L,T=audio/mpeg]
RewriteRule ^media/download/[^/]+$ - [L,T=application/octet-stream]

SetEnvIf Request_URI ^/media/download/ force-download

<IfDefine force-download>
    Header set Content-Disposition attachment
    Header set Content-Type application/octet-stream
</IfDefine>

APACHE mod_rewrite change variable name in query string

it should still fix some issue Parsing the query string with mod_rewrite is a bit of a pain, has to be done with RewriteCond and using %n replacements in a subsequent RewriteRule, probably easier to manually break up the original query string in PHP.
The full query string can be found (within PHP) in $_SERVER['QUERY_STRING'].

code :

$params = array();
foreach (explode("&", $_SERVER['QUERY_STRING']) as $cKeyValue) {
    list ($cKey, $cValue) = explode('=', $cKeyValue, 2);
    $params[urldecode($cKey)] = urldecode($cValue);
}

// Would result in:

$params = array('custom cbid' => 123,
                'blahblahblah' => NULL,
                'name' => example);

How to change variable content getting the variable name from a data-attribute in a loop?

Any of those help If I understand what you need to do, you should try to use eval()

code :

var a = $('#el').attr('data-x');
for (var i = 0; i <= 2; i++) {
    eval(a + "++");
    $('#'+a).text(eval(a));
    if (i === 0) { a = $('#el').attr('data-x1')} 
    else if (i === 1) { a = $('#el').attr('data-x2');} 
    else if (i === 2) { a = $('#el').attr('data-x3');}
}

flask change jinja2 variable content in a template and display the new content

By : dls

fixed the issue. Will look into that further Jinja2 templates cannot change a page without the browser refreshing, they are simply a way for you to place dynamic content on a page before sending it to the browser. To change your page while on the client's browser you'll need to use javascript.
You can perform an ajax call from the browser back to your server, which then the server can send back the updated log variable. However, you'll then need to use javascript again to update that text on the DOM.
