PHP - Add Column And Value Existing Csv
Hi
Similar TutorialsMy Php Buddies, I have mysql tbl columns these:
id: Now, I want to display their row data by excluded a few columns. Want to exclude these columns: date_&_time account_activation_code account_activation_status id_verification_video_file_url password
So, the User's (eg. your's) homepage inside his account should display labels like these where labels match the column names but the underscores are removed and each words' first chars CAPITALISED:
Id: 1
For your convenience only PART 1 works. Need help on Part 2 My attempted code:
PART 1 <?php // Check connection if ($conn->connect_error) { die("Connection failed: " . $conn->connect_error); } // Query to get columns from table $query = $conn->query("SELECT COLUMN_NAME FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_SCHEMA = 'members' AND TABLE_NAME = 'users'"); while($row = $query->fetch_assoc()){ $result[] = $row; } // Array of all column names $columnArr = array_column($result, 'COLUMN_NAME'); foreach ($columnArr as $value) { echo "<b>$value</b>: ";?><br><?php } ?> PART 2 <?php //Display User Account Details echo "<h3>User: <a href=\"user.php?user=$user\">$user</a> Details</h3>";?><br> <?php $excluded_columns = array("date_&_time","account_activation_code","account_activation_status","id_verification_video_file_url","password"); foreach ($excluded_columns as $value2) { echo "Excluded Column: <b>$value2</b><br>"; } foreach ($columnArr as $value) { if($value != "$value2") { $label = str_replace("_"," ","$value"); $label = ucwords("$label"); //echo "<b>$label</b>: "; echo "$_SESSION[$value]";?><br><?php echo "<b>$label</b>: "; echo "${$value}";?><br><?php } } ?> PROBLEM: Columns from the excluded list still get displayed. Edited November 19, 2018 by phpsaneI spent some time "Googling" today but all I found was how to create PDFs on the fly. What I wonder is if it is possible to print text on an existing PDF. And if so, could I get some pointer where to obtain this knowledge? Simply put. I have a PDF form that is not yet filled out. I would like to be able to look up an address and other information in a database, and use that information to print on the existing PDF file. Any help is much appreciated.

The existing connection is a persistant connection. Okay so I have a time in the format yyyy-mm-dd that is pulled from a MySQL array row and I need to add one month to it then echo that out. I assume it has something to do with the strtotime() and date() functions but I have tried every combination and cannot figure it out. Can I get some assistance please and thank you?

Code: [Select] <?php if(!isset($_COOKIE['testCookie'])){ setcookie("TestCookie", "username", time() + (24 * 60) ) } ?> <html>....</html> At the moment my page just doesn't get past this piece of code any ideas? Cheers Hi guys, using the code below within an admin panel to create a drop down allowing the user to select the profiles they wish to assign to the record they're creating, problem we have is that once a record is created, if they need to edit it for what ever reason the selected profile option isn't sticking. I've played around with lots of variants of if existing_record to try and get it add selected="selected" into the code but failed at every attempt, any advice gratefully received. Code: [Select] <?php // List only breeder profiles in the database echo '<select name="profile" class="textinput noborder">'; echo '<option value="any">Any</option>'; $qryGetDistinctProfile = "SELECT * FROM profiles ORDER BY title ASC"; $resGetDistinctProfile = mysql_query($qryGetDistinctProfile,$connection) or die(mysql_error()); if(mysql_num_rows($resGetDistinctProfile) > 0){ $id = mysql_result($resProfile, 0, "id"); while ($row = mysql_fetch_assoc($resGetDistinctProfile)){ echo '<option value="'.$row['id'].'" >'.$row['title'].'</option>'; } } echo '</select>'; ?> I would like to support UTF-8 on my website but am unsure - and quite fearful - whether it will break my existing code or not?! I looked at http://us3.php.net/mbstring(), but worry that I'm going to miss something.

I'm not sure if any problems would arise with #1 or #3 or elsewhere, and would really appreciate a second set of eyes on this code!! requinix said switching is a good idea, but I'm pretty freaked out that I'm going to break things and create a big security hole?!

I can currently set the amount of links to display per page but that's it. I would like to be able to truncate the links to all the pages using pagination. Any help would be greatly appreciated!

Thanks guys.... I have a table with lots of records. My table has the following field, with records containing either NULL or '1' that I need to modify. My root directory (in the actual file system) has several subdirectories, one of which is a "main" site, while the others are individual user sites. Every subdirectory has their own .htaccess file, but it's the root .htaccess file that is the topic. I have tried to create rewrite rules myself, but I can't get the rewrite conditions to properly check for the folder existing.
/main/lots-of-files
/homer/lots-of-files
/marge/lots-of-files
/bart/lots-of-files
/lisa/lots-of-files
/maggie/lots-of-files
/.htaccess
So this is the root of my web server. When I go to sites.example.com I see the directory listing above. I want sites.example.com to point to "/main/" instead of "/". Not only that, but I want everything not specifically pointing to any user dubdirectory to rewrite to /main/.
These should not rewrite to /main/, because these directories exists in root*:
/homer/index.php
/marge
/lisa/pictures/profile.gif
* The files may not exist in those positions, as /homer/, /marge/, /bart/, /lisa/ and /maggie/ all has a .htaccess file with their own rewrite rules.
These should rewrite to /main/:

/philip
/bender/bending/rodriguez.php
/basically/anything-not-existing-as-a-directory
/some-file.txt
Edited by Berre, 07 January 2015 - 12:17 PM. Hello,
First time asking technical question in a forum so I beg pardon for errors.
I have a third party blog module installed on opencart. The original coder helped me to fix some bugs, but he is not answering anymore to emails.
I would like to add a simple pagination to the "latest articles" part, because at the moment the website display the exact number declared in "article limit" and does not show pagination if articles shown are less than the total.
the code from "article_by_type.php" line 85 is the following:
/*recent_article*/ if ($setting['article_type']=='recent_article') { $data = array( 'sort' => 'p.date_added', 'order' => 'DESC', 'start' => 0, 'limit' => $article_limit ); $articles = $this->model_news_article->getArticles($data); }another file "article_list.php" at line 88 and 214 already have pagination: $this->data['article_ajax_load'] = $this->getArticle($article_category_id,$page,$limit,$description_limit);can anyone help add pagination to "article_by_type.php" or adapt the existing pagination code to it ?

Hello! I found this code from github. https://github.com/gburtini/Learning-Library-for-PHP and I want to know if its possible to add variables to it and what changes needed to be done to the whole script. $xs and $ys I want replace them and add two more. The whole code is he <?php require_once 'function.php'; function ll_nn_predict($xs, $ys, $row, $k) { $distances = ll_nearestNeighbors($xs, $row); $distances = array_slice($distances, 0, $k); $predictions = array(); foreach($distances as $neighbor=>$distance) { $predictions[$ys[$neighbor]]++; } asort($predictions); return $predictions; } function ll_nearestNeighbors($xs, $row) { $testPoint = $xs[$row]; $distances = _ll_distances_to_point($xs, $testPoint); return $distances; } function _ll_distances_to_point($xs, $x) { $distances = array(); foreach($xs as $index=>$xi) { $distances[$index] = ll_euclidean_distance($xi, $x); } asort($distances); array_shift($distances); return $distances; } and the function.php that is required is this: <?php function ll_transpose($rows) { $columns = array(); for($i=0;$i<count($rows);$i++) { for($k = 0; $k<count($rows[$i]); $k++) { $columns[$k][$i] = $rows[$i][$k]; } } return $columns; } function ll_mean($array) { return array_sum($array)/($array); } function ll_variance($array) { $mean = ll_mean($array); $sum_difference = 0; $n = count($array); for($i=0; $i<$n; $i++) { $sum_difference += pow(($array[$i] - $mean),2); } $variance = $sum_difference / $n; return $variance; } function ll_euclidean_distance($a, $b) { if(count($a) != count($b)) return false; $distance = 0; for($i=0;$i<count($a);$i++) { $distance += pow($a[$i] - $b[$i], 2); } return sqrt($distance); } I just want to know where is the variables in those 2 scripts and add more as I'm not well versed in using PHP. Thank you! Hello Everyone, I've successfully created a form script to check to make sure all my fields are filled out. However, I wanted to create an if statement to check and see if the email address is valid and it contains both and "@", "." symbols. If not then echo '' This is not a Valid email address " if its not correct. Could someone tell me the proper way to write this and incorporate this into my existing script below. Thank you all Again for your Help thanks mrjap1 Code: [Select] // Confirm All feild were filled out when submit button was pressed if($name && $email && $username && $password && $confirm_password) { // Confirm that the NAME that you used is NOT greater than 30 characters if(strlen($name)>24) { echo "<h2><center>YOUR NAME IS TOO LONG!!!!</center></h2><br>"; } // Confirm that the EMAIL that you used is NOT greater than 25 characters if(strlen($email)>25) { echo "<h2><center>YOUR EMAIL IS TOO LONG!!!!</center></h2><br>"; } // Confirm that the USERNAME that you used is NOT greater than 10 characters if(strlen($username)>10) { echo "<h2><center>YOUR USERNAME IS TOO LONG!!!!</center></h2><br>"; } else { // Confirm that the PASSWORD that you used MATCH & Between 6 and 15 characters if(strlen($password)>10 || strlen($password)<6) { echo "<h2><center>YOUR PASSWORD MUST BE BETWEEN 6 and 15 CHARACTERS!!!!</center></h2><br>"; } if($password == $confirm_password) { I need some guidance in regards to adding Login with Facebook.
Is this something which is easily done? Currently, I'm using UserCake:

How much testing and QA is necessary for this type of work?
EDIT: sorry - new to posting guidelines - using XAMPP with mysql 5.1.44 (I think this is correct!!) Newbie question he I have successfully created a form that that displays students (based on a selected lesson/group/date) with the ability to enter scores. I'm now trying to set the form up so that if data already exists then it is displayed in the form. Eg: if a member of staff choses group 7AS, lesson 1, 24/09/2010 and another member of staff has entered a score already for one student it shows up in the <select> drop down by using Code: [Select] <option>" . $scorevalue . "</option> I had this working at one point but have made a change somewhere and cannot get it working again! can anyone spot an obvious mistake I am making? The code I am using is as follows: Code: [Select] <input type="hidden" name="tutor" value="<?php echo $_GET["tutor"]; ?>" /> <input type="hidden" name="date" value="<?php echo $_GET["date"]; ?>" /> <input type="hidden" name="lesson" value="<?php echo $_GET["lesson"]; ?>" /> <?php error_reporting(-1); $con = mysql_connect("localhost","root",""); if (!$con) { die('Could not connect: ' . mysql_error()); } mysql_select_db("lakeside", $con); $result = mysql_query("SELECT students.admin, students.fname, students.surname, students.tutor FROM students WHERE tutor='$_GET[tutor]' ORDER BY students.tutor, students.surname"); echo "<table class='scores'> <tr> <th>Admin</th> <th>Firstname</th> <th>Surname</th> <th>Tutor</th> <th>Score</th> <th>Code</th> <th>Comment</th> </tr>"; while($row = mysql_fetch_array($result)) { $sqlstatement = "SELECT * FROM scores where admin = '" . $row['admin'] .

Ultimately, I’m trying to integrate the buy_video.php file’s ‘$earned_amount’ into a web script’s existing transaction file. Here are a couple of lines from that transaction file: $this_day_video_earn = $db->rawQuery("SELECT SUM(amount - admin_com) AS sum FROM ".T_VIDEOS_TRSNS." c WHERE `time` >= ".$day_start." AND `time` <= ".$day_end." AND user_id = ".$pt->user->id); $today_earn = $this_day_ads_earn[0]->sum + $this_day_video_earn[0]->sum ; and $trans = $db->where('user_id',$user->id)->orderBy('id','DESC')->get(T_VIDEOS_TRSNS); That may not be enough info, but I’d like assistance changing those lines to: $this_day_video_earn = $db->rawQuery("SELECT SUM(earned_amount) AS sum FROM “.T_VIDEOS.” c WHERE time >= “.$day_start.” AND time <= “.$day_end.” AND user_id = ".$pt->user->id); $trans = $db->where('user_id',$user->id)->orderBy('id','DESC')->get(T_VIDEOS);
I tried those changes without success.
