  1. I have developed a Python/Selenium script to automate some web operations that I need to do. I have this successfully running on my local PC. Can I upload this to TCH and run it there, so that I can then give other users access to it? This would seem to require a browser (I'm currently using Chrome) to be running on TCH (maybe headlessly) so that Selenium can send commands to it. Can this be done? How? Thanks - Rowan
  2. I am searching for the best way of storing, cataloguing and making available all the family history related photographs that I have. I have literally thousands of photos passed down to me from my parents and grandparents, many going back into the 19th century. I am slowly progressing with digitising these, and photoshopping them to remove the most obvious blemishes and deteriorations. I would like to make these available to me and to members of my family and their descendants now and in the future. Ideally for each image I would like to store: Date of photo Who took it What the event (if
  3. I'm having a problem on a website that I develop. It seems that sometimes when I call session_start(), it fails to find a previously opened session, and opens a new one, which means that I lose all my session variables. Here's a section of log: [27-Feb-2020 17:39:43.496 GMT 0] on localhost, L_TRACE MemberId 18 attempted to login with PasswordStatus = 4 at line 169 in file: /home/sylvest/public_html/swchoir/do_login.php [27-Feb-2020 17:39:43.497 GMT 0] on localhost, L_TRACE Session ID = qdgs4obtlicrlcgnp6tc179e87, $_SESSION = {"breadcrumbs":[{"shortname":"Lo
  4. I'm trying to debug some rewrite rules, without much success currently. If I could see the log, showing what text was used to match conditions in Rewrite Cond and Rewrite Rule statements, and what the result was, I would be more likely to be able to find the error. I have tried enabling logging in the .htaccess file and it says "ErrorLog not allowed here". How do I enable rewrite logging on TCH? If I can't, how do I debug my rules? Thanks - Rowan
  5. In my web application, I am trying to execute the SQL query: SELECT b.BuildNum,c.MenuName FROM `Members$BuildClasses` AS mc JOIN BuildClasses AS c ON mc.BuildClassId = c.BuildClassId JOIN Builds AS b ON c.BuildClassId = b.BuildClassId WHERE mc.MemberId = " . $_SESSION['login_memberid'] . " AND b.Status > '0' AND mc.Status > '0' ORDER BY BuildNum by executing the statement: $result = mysqli_query($dbh, $sql); on line 444 in file: /home/sylvest/include/functions.php (where $sql is equal to the above string) When I do this I'm getting this error: [26-Feb-2019 12:40:
  6. My site uses the function json_encode(). Previously I had my own php.ini file that included the line "extension = json.so". Everything used to work fine. But for a different reason I had to stop using my PHP.INI file and start using one generated by CPanel. Now I'm getting the error "Fatal error: Call to undefined function json_encode() in /home/sylvest/include/var_dump_ret.php on line 16". The CPanel generated INI file does not contain the line "extension = json.so" and I guess that this is why it's stopped working. So my question is, how either using CPanel or within my PHP code do I load th
  7. I have a requirement for my PHP pages sometimes to send files (e.g. images, CSS files, JS files, fonts) to the client. The normal way to do this seems to be to use the readfile() function, but I understand that this reads the whole file into memory and then sends it to the client, which will cause problems if it is a very large file. I understand that there is an Apache module mod_xsendfile which does a better job, but Support tell me that this is not available on my shared server. So my question is, what is the best/most efficient way of sending files to the client in PHP, without mod_xsendfi
  8. Hi, I have an HTML form with a large number of inputs on it. Most of them are <select> elements each with 6 options. There are currently 1295 of these selects, plus a few other inputs, but the number is not constant, since the form is generated dynamically, and it depends on the number of rows and the number of columns for the currently selected period. In the $_POST array it seems that I am only receiving 1000 values, which means that some of the ones I need I am not receiving. I have tried changing the value of max_input_vars in /home/myaccount/public_html/php.ini from 1000 to 1000
  9. I have the following SQL being executed by a mysqli_query() statement in my PHP code: DROP TEMPORARY TABLE IF EXISTS tmptable; CREATE TEMPORARY TABLE tmptable SELECT * FROM Members WHERE MemberId = '105' AND Status > '0'; UPDATE tmptable SET RecordId = '', Status = '0', ChangedBy = '4', ChangedOn = '2017-05-21 19:03:39'; UPDATE Members SET Status = '0' WHERE MemberId = '105' AND Status > '0'; INSERT INTO Members SELECT * FROM tmptable; It is being rejected with the following error: Errno: 1064 Error: You have an error in your SQL syntax; check the manual that corresponds to y
  10. I have a web page which under certain conditions forwards to another one using the statement: header($next_page); where $next_page == "Location: http://www.sylvesterbradley.org/swchoir/index.php?v=1493894983" This causes a 500 error. I am reasonably sure that I have sent no output at all (other than to a log file) before the header statement. In any case, on other occasions where I have done this I seem to get a warning, which in this case is not happening. I see nothing in any error_log files that I am aware of (that is /home/sylvest/error_log and /home/sylvest/pubic_html/
  11. I am trying to use the PHP password hashing module in my code, but the following line: $hasher = new PasswordHash(8, false); is giving me the error: Fatal error: Class 'PasswordHash' not found in /home/myaccount/public_html/directory/edit_member.php on line 124 I am running PHP version 5.6.30. I thought that all versions from 5.5.0 onwards had this module? What do I have to do to enable me to use this? Thanks - Rowan

  13. Well, it sort of helps. Thanks for providing this link. But I think my most straightforward answer is to remember to use Firefox or Chrome if I want to access the TCH forum. Of course I will usually forget this until I find that I can't paste :-(. Thanks - Rowan
  14. Bruce, Thanks for your reply. Why is it that I can't do an internal rewrite to a location above public_html? Here is an exerpt from http://httpd.apache.org/docs/2.2/mod/mod_rewrite.html#rewriterule The Substitution of a rewrite rule is the string that replaces the original URL-path that was matched by Pattern. The Substitution may be a: file-system path Designates the location on the file-system of the resource to be delivered to the client. Substitutions are only treated as a file-system path when the rule is configured in server (virtualhost) context and the first component o
  15. I have found many discussions on the web around this topic. Some say that a rewrite rule assumes that the redirect path is a file system path if the first element of the path (/home in this case) exists at the root of the file system (which it obviously does in this case). Otherwise it assumes that it is relative to the Document Root. Other people imply that redirect to a file system path is not permitted for .htaccess files for security reasons, but that you can use an Alias as a work around. Is it in fact possible to write a RewriteRule that will work in an .htaccess file on a TCH server
