| | Re: PHP learning [phpacademy](https://phpacademy.org/) - learning by watching videos, various PHP forums like [Daniweb](http://www.daniweb.com) :-), [Stackoverflow](http://stackoverflow.com/questions/tagged/php), a good [book](http://www.amazon.com/Beginning-PHP5-Apache-MySQL-Development/dp/0764579665) on PHP, the [documentation](http://www.php.net/manual/en/) on the PHP.net site (comprehensive, free, but sometimes harder to get through it) and a lot of experimenting - set up LAMP or XAMP and go for it. And do … |

 | Describe your tables in a way that you can create forms and generate queries. A simple way of doing it would be to have table fields stored in an associative array where keys would be field names and values would be field types. That way you can tell whether to … |

| | Where is the information about the logged-in user stored? Let's assume that is stored in the session in the `$_SESSION['loggedin_username']` variable. Now while fetching rows you have to check whether the fetched username equals to the logged-in username.

| | For one thing you are missing quotes arround associative index names. Since the array elements are complex variables you should also enclose them in curly braces to get them parsed properly in a double quoted string. Another issue is that you echo the if condition which is not right. Then … |
| | The code on line 9 is wrong, it wont return what you expect. You could change your query a bit and ad `AS` to the substring expression in the query: SELECT runners.raceid, SUBSTRING(runners.raceid,1,4) AS raceyear,... and then change line 9 in the code to: echo $row['raceyear']; |

 | Your condition is wrong since it checks if either submit is set (which always is after submitting) or $service_name has some text. The condition is always true and the values are inserted (if they do not exist). The correct condition would be using && (and): if($submit=='submit' && strlen($service_name) > 0 … |

| | There might be some errors in your script(s), but your web server is not telling you about them since most probably the display of errors is turned off. Change the following settings in your php.ini: error_reporting=E_ALL display_errors=On and restart your web server. The errors could be in the included inc/config.php … |
 | On line 5 you are trying to write date object into the text file. It won't go. Also the third argument to the fwrite is optional string leght. I doubt you wanted to use it that way. Change line 5 to something like: fwrite($file, $ip . ' ' . $dt->format('Y-m-d … |
| | Decide on how many characters you can display. Then change line 30 from: <td ><?php echo $row['service_content']; ?></td> to: <td > <?php $contentLength = strlen($row['service_content']); // check if the length of the content exceeds max number of chars e.g. 120 if($contentLength > 120) { echo substr($row['service_content'], 0, 120) . '...'; … |
| | Check what the $array content is. Is it an array of objetcs (this is how you reffer to each row)? To check the contents of the array insert this temporary debug code after line 5 in the second code snippet: die(print_r($array, 1)); This will display the contents of the $array … |

| | Re: forget password Here is and example of a script that resets the password and mails new password to the user. http://www.daveismyname.com/tutorials/php-tutorials/reset-password-script/ I prefer slightly different approach.

| | You should not echo any output before the header command. Remove line 56: echo "<p class='red-info'> Record Saved! </p>"; so the headers can be sent. This command is pointless anyway since the page would get redirected. |
 | A bit more code would help. Where do you echo it? Maybe it gets changed somewhere in the process? contest[name] the index should be enclosed in quotes: contest['name'] and enclosed in curly braces if used in a double quoted string: ...id="contest-name" name="{contest['name']}" value="' ... |
| | What was the problem with the layout? TCPDF is quite flexible and I did not have problems creating nice tables.  |
| | To recap the above two posts: // check whether $_GET has any value and if the value is valid // (you might use some more proper validation depending on the value of the movie ID) if(isset($_GET['movie_id']) && !empty($_GET['movie_id'])) { $query = "SELECT movie_name,movie_year,movie_director,movie_leadactor,movie_type,movie_running_time,movie_cost,movie_takings FROM movie WHERE movie_id= " . mysql_real_escape_string($_GET['movie_id']); … |
| | Maybe the simplest way would be to address the array element directly: $eng['profile_permission'] = 'You belong to ' . $group . ' with a permission of ' . $permission .''; or using double quotes: $eng['profile_permission'] = "You belong to $group with a permission of $permission"; |

| | > i don't understand. how does this solve my problem? If number of [affected rows](http://www.php.net/manual/en/function.mysql-affected-rows.php) equals 0 no rows were deleted. That might be the case if no rows matched $idURL. But to check there are no other issues, use simple debugging technique - insert this code right after line … |

| | Check out if the `$insertGoTo` variable has same value in both cases.

And also: you can simplify the header function like this: header("Location: … |
 | You can do it all in Javascript if you do not need server processing. In this case just write a function to convert number to words and fire it on keyup event. Now, if you need to process numbers on a server (as it seems from your post) then you … |
