function getDate($campid) Morning All, Should be a quick one for the seasoned veterans! I'm learning the in's and out's of sanitizing my variables for input into my database (mysql). The following is my code; Code: [Select] $Username = mysql_real_escape_string($_POST['username']); $PWord = mysql_real_escape_string($_POST['pword']); $Email = mysql_real_escape_string($_POST['email']); $Fullname = mysql_real_escape_string($_POST['fullname']); $Address_1 = mysql_real_escape_string($_POST['address_1']); $Address_2 = mysql_real_escape_string($_POST['address_2']); $City = mysql_real_escape_string($_POST['city']); $Zip = mysql_real_escape_string($_POST['zip']); $Country = mysql_real_escape_string($_POST['country']); The following is my output; Error executing INSERT statement - INSERT INTO tblUser(User_Name, Full_Name, Email, Address_1, Address_2, City, Zip, Country, PWord)VALUES ('','','','','','','','','') Any ideas? Also; is mysql_real_escape_string valid for use on all types of input from the input box? Ok, starting around line 137 with the functions..... Commented well. Just not sure If im doing it right. Any help greatly appreciated. Basic stuff and still learning. Just trying to figure out if Im passing by reference correctly or if not how to do it. Thanks. php File is attached but heres a snippet. Thanks in advance. Peace, Adam // The grand total and the item total need to be passed BY REFERENCE. function show_table_contents($cart_items, $table, &$grand_total, &$item_total) Im trying to understand the code below. (taken from an O'REILLY book) Im trying to get my head around this, so can anyone tell me if im thinking about this in the right way; The function (fix_names) borrows the values from $a1,$a2 and $a3 and puts them into $n1,$n2, and $n3. It then processes the strings contained within these newly created variables and then returns the processed values back into $a1,$a2,and $a3? The variables $n1,$n2, and $n3 cannot be echoed as they were created within the function.? Please correct me if im wrong. Code: [Select] <html> <head> </head> <body> <?php $a1 = "EDWARD"; $a2 = "thomas"; $a3 = "wriGHT"; fix_names($a1,$a2,$a3); echo $a1." ".$a2."

So: part of the subclass reads: Code: [Select] function __construct($v1, $v2, $v3) { $this->speed[] = $v1; // I dont like this either, it is not elegant. I tried to put an array as argument of the constructor and send the parameters $this->speed[] = $v2; // from the object being created, but it did not work, so I leave it like this for now, but I would have preferred to put that $this->speed[] = $v3; // array and then populate it by some looping. } // METHOD TO REPORT TABLE OF ACCELERATION public function acceleration() { return $this->acceleration1 = ($this->speed[1] - $this->speed[0])/5; // I actually need to return the other two speed differences from the other stages, but as you know, once the first return acts, it exits the function // so sure this "return" has to be abandoned and the results of the function have to be printed otherwise. That is the question. } =================================== And now from the Object file I am trying to call the function, but of course, I only get one value, even if I write 3 times return Code: [Select] $objeto = new Motorbike($v1, $v2, $v3); echo '<p>The speeds are ' . $objeto->acceleration() . '</p>'; // Yes, this call works, of course, but that is about it. I cant print any other result. Thanks a lot not sure if this is possible but i do not know how to return multiple values and read them where the call was made. Code: [Select] $string = "clause1"; func1($string); // somehow read the response and use the return values seperately. // both $string2 and $string3 Code: [Select] function func1($input) { if ($input == "clause1") { $string2= "value2"; $string3= "value6"; } if ($input == "clause2") { $string2= "value3"; $string3= "value7"; } if ($input == "clause3") { $string2= "value4"; $string3= "value8"; } if ($input == "clause4") { $string2= "value5"; $string3= "value9"; } return ($requesttype, $messagetitle); } Code: [Select] header("Location: index.php?x=y") , i had seen people having this problem when i was asking too.. about adding GET values to a change header function... Anyone still need this help? Moodle 2.5 *nix server Theme: Essential ---------------------- Hi Folks I have a small mind bender in how php is returning results from a mysql query. There are two issues: 1) The mysql query from phpmyadmin is correct, while the php function that handles the query from the website is not. 2) It takes a very long time to run this query with php, 30 seconds to over a minute. Phpmyadmin is rather quick (Query took 0.0239 seconds). The query is:
SELECT u.firstname AS 'Name' , u.lastname AS 'Surname', c.shortname AS 'Course', (
CASE
WHEN gi.itemname LIKE '%summative%' THEN 'SUMMATIVE'
WHEN gi.itemname LIKE '%formative 2%' THEN 'FORMATIVE 2'
ELSE 'MC'
END) AS 'Assessment', from_unixtime(gi.timemodified, '%d/%m/%y') AS 'Date',
IF (ROUND(gg.finalgrade / gg.rawgrademax * 100 ,2) > 70,'Yes' , 'No') AS Pass, ROUND(gg.finalgrade / gg.rawgrademax * 100 ,2) AS 'Mark', ROUND(gg.finalgrade / gg.rawgrademax * 100 ,2) AS 'Mark'
FROM mdl_course AS c
JOIN mdl_context AS ctx ON c.id = ctx.instanceid
JOIN mdl_role_assignments AS ra ON ra.contextid = ctx.id
JOIN mdl_user AS u ON u.id = ra.userid
JOIN mdl_grade_grades AS gg ON gg.userid = u.id
JOIN mdl_grade_items AS gi ON gi.id = gg.itemid
JOIN mdl_course_categories AS cc ON cc.id = c.category
WHERE gi.courseid = c.id
AND gi.itemname != 'Attendance'
AND u.firstname LIKE '%03%'
AND gi.itemname LIKE '%mative%'
ORDER BY `Name` , `Surname` , `Course`, `Assessment` ASC
When I run the query in phpmyadmin , it gives back;Name Surname Category Module Course Assessment Date Competent Mark G03 Itumeleng Velmah Mokwa Fundamentals Communications CO1 119472 FORMATIVE 2 07/04/14 Yes 100.00 G03 Itumeleng Velmah Mokwa Fundamentals Communications CO1 119472 SUMMATIVE 07/04/14 Yes 100.00 G03 Itumeleng Velmah Mokwa Fundamentals Communications CO2 119457 FORMATIVE 2 05/04/14 Yes 100.00 G03 Itumeleng Velmah Mokwa Fundamentals Communications CO2 119457 SUMMATIVE 05/04/14 Yes 88.00 G03 Lally Sheila Mokane Fundamentals Communications CO1 119472 FORMATIVE 2 07/04/14 NYC 59.00 G03 Lally Sheila Mokane Fundamentals Communications CO1 119472 SUMMATIVE 07/04/14 Yes 90.00 G03 Lally Sheila Mokane Fundamentals Communications CO2 119457 FORMATIVE 2 05/04/14 Yes 100.00 G03 Lally Sheila Mokane Fundamentals Communications CO2 119457 SUMMATIVE 05/04/14 Yes 98.00And it is perfect so I have no issues with that. Now in php I call;
function print_overview_table_groups($COURSE, $choosegroup, $fromdate, $todate, $numarray)
{
global $DB;
//check data
if(!$choosegroup){
die('No Records To Display.');
}
$thisgroup = $numarray[$choosegroup];
$sql = "SELECT DISTINCT u.firstname AS 'Name' , u.lastname AS 'Surname',

END) AS 'Category',

c.shortname AS 'Course',
(CASE
WHEN gi.itemname LIKE '%summative%' THEN 'SUMMATIVE'
WHEN gi.itemname LIKE '%formative 2%' THEN 'FORMATIVE 2'
ELSE 'MC'
END) AS 'Assessment', from_unixtime(gi.timemodified, '%d/%m/%y') AS 'Date',
IF (ROUND(gg.finalgrade / gg.rawgrademax * 100 ,2) > 70,'Yes' , 'NYC') AS Competent, ROUND(gg.finalgrade / gg.rawgrademax * 100 ,2) AS 'Mark'

AND u.firstname LIKE '%03%'
AND gi.itemname LIKE '%mative%'
ORDER BY `Name` , `Surname` , `Course`, `Assessment` ASC";
return $DB->get_records_sql($sql);
}
This is returned to the index.php page from the function call;$lists = print_overview_table_groups($COURSE, $choosegroup, $fromdate, $todate, $numarray); print "<pre>"; print_r($lists); print "</pre>";The result is baffling...

Thank You Edited February 8, 2020 by karthicbabuHi, My company has 240+ locations and as such some users (general managers) cover multiple sites. When I run a query to pull user information, when the user has multiple sites to his or her name, its adds the second / third sites to the next columns, rather than wrapping it inside the same table cell. It also works the opposite way, if a piece of data is missing in the database and is blank, its pull the following columns in. Both cases mess up the table and formatting. I'm extremely new to any kind of programming and maybe this isn't the forum for this question but figured I'd give it a chance since I'm stuck. The HTML/PHP code is below: <table id="datatables-column-search-select-inputs" class="table table-striped" style="width:100%"> <thead> <tr> <th>ID</th> <th>FirstName</th> <th>LastName</th> <th>Username</th> <th>Phone #</th> <th>Location</th> <th>Title</th> <th>Role</th> <th>Actions</th> </tr> </thead> <tbody> <?php //QUERY TO SELECT ALL USERS FROM DATABASE $query = "SELECT * FROM users"; $select_users = mysqli_query($connection,$query);
// SET VARIABLE TO ARRAY FROM QUERY while($row = mysqli_fetch_assoc($select_users)) { $user_id = $row['user_id']; $user_firstname = $row['user_firstname']; $user_lastname = $row['user_lastname']; $username = $row['username']; $user_phone = $row['user_phone']; $user_image = $row['user_image']; $user_title_id = $row['user_title_id']; $user_role_id = $row['user_role_id'];
// POPULATES DATA INTO THE TABLE echo "<tr>"; echo "<td>{$user_id}</td>"; echo "<td>{$user_firstname}</td>"; echo "<td>{$user_lastname}</td>"; echo "<td>{$username}</td>"; echo "<td>{$user_phone}</td>";

Hi all, Just curious why this works: Code: [Select] while (($data = fgetcsv($handle, 1000, ",")) !== FALSE){ $import="INSERT into $prodtblname ($csvheaders1) values('$data[0]','$data[1]','$data[2]','$data[3]','$data[4]','$data[5]','$data[6]')"; } And this does not: $headdata_1 = "'$data[0]','$data[1]','$data[2]','$data[3]','$data[4]','$data[5]','$data[6]'"; while (($data = fgetcsv($handle, 1000, ",")) !== FALSE){ $import="INSERT into $prodtblname ($csvheaders1) values($headdata_1)"; }it puts $data[#'s] in the database fields instead of the actual data that '$data[0]','$data[1]'... relates to. I wrote a script to create the values in $headdata_1 based on the number of headers in $csvheaders1 but can't seem to get it working in the sql statement. Thanks Hi all, I'm a first time poster here and I would really appreciate some guidance with my latest php challenge! I've spent the entire day googling and reading and to be honest I think I'm really over my head and need the assistance of someone experienced to advise the best way to go! I have a multi dimensional array that looks like (see below); the array is created by CodeIgniter's database library (the rows returned from a select query) but I think this is a generic PHP question as opposed to having anything to do with CI because it related to working with arrays. I'm wondering how I might go about searching the array below for the key problem_id and a value equal to a variable which I would provide. Then, when it finds an array with a the matching key and variable, it outputs the other values in that part of the array too. For example, using the sample data below. How would you recommend that I search the array for all the arrays that have the key problem_id and the value 3 and then have it output the value of the key problem_update_date and the value of the key problem_update_text. Then keep searching to find the next occurrence? Thanks in advance, as above, I've been searching really hard for the answer and believe i'm over my head! Output of print_r($updates); CI_DB_mysql_result Object ( [conn_id] => Resource id #30 [result_id] => Resource id #35 [result_array] => Array ( ) [result_object] => Array ( ) [current_row] => 0 [num_rows] => 5 [row_data] => ) Output of print_r($updates->result_array()); Array ( [0] => Array ( [problem_update_id] => 1 [problem_id] => 3 [problem_update_date] => 2010-10-01 [problem_update_text] => Some details about a paricular issue [problem_update_active] => 1 ) [1] => Array ( [problem_update_id] => 4 [problem_id] => 3 [problem_update_date] => 2010-10-01 [problem_update_text] => Another update about the problem with an ID of 3 [problem_update_active] => 1 ) [2] => Array ( [problem_update_id] => 5 [problem_id] => 4 [problem_update_date] => 2010-10-12 [problem_update_text] => An update about the problem with an ID of four [problem_update_active] => 1 ) [3] => Array ( [problem_update_id] => 6 [problem_id] => 4 [problem_update_date] => 2010-10-12 [problem_update_text] => An update about the problem with an ID of 6 [problem_update_active] => 1 ) [4] => Array ( [problem_update_id] => 7 [problem_id] => 3 [problem_update_date] => 2010-10-12 [problem_update_text] => Some new update about the problem with the ID of 3 [problem_update_active] => 1 ) ) Hello all, I have some piece of code that is nested like this $variable = 'This is a global argument'; function parentFunction($variable) { function childFunction() { echo 'Argument of the parent function is '.$GLOBALS['variable']; } childFunction(); } parentFunction(5); What I want to know is - Is there a way to access a variable from the parent function without passing arguments to the child function? (Something like how classes have parent::?). I don't want to use $GLOBALS because it might cause some variable collision, and I didn't want to pass arguments because incase I decide to change the arguments in the parent function I'd have to do it in the child function aswell. From my searching around in the Internet it seems like this is not possible, but if theres a slight chance that there might be something out there, i'm willing to give it a shot . Thanks in advance I have this function completely written in my class file that I am working on. The point to this function is to be able to check the login of a user or administrator for either of the control panels associated with my site. It will check the session intime as well as the page / module referenced. Once it passes all those checks, it will check and ensure the emailaddress/password stored in the current session still holds true and the account is still active... if the account is still active it will update the lastActivity as well as update all of the session variables with what is currently in the database. What I am looking for is basically a look at the function, see if it looks good.. If there is any part to it that could create security holes for the site just off the login function itself... Usage: $q->validUser($_SESSION['user'], $_mod); <?php function validUser($sess, $p) { if ($sess['inTime'] == '' && $p != 'login' && $p != 'logout') { session_destroy(); $login = '0'; $_int = ''; return $login; } else if ($sess['inTime'] < time()-3600 && $p != 'login') { $sess['inTime'] = ''; session_destroy(); $this->check_login($sess, $p); } else { $this->user = $sess['emailAddress']; $this->pass = $sess['password']; $login = $this->sql_query("SELECT * FROM users WHERE emailAddress = '".$this->user."' AND password = '".$this->pass."' AND status = '1' LIMIT '1'"); if ($login = $this->sql_numrows($login) < 1) { $sess['inTime'] == ''; session_destroy(); $login = '0'; } else { // logged in, lets update the database for last_activity AND the session. $this->sql_query("UDATE users SET lastActivity = '".now()."' WHERE emailAddress = '".$this->user."'"); $login = $this->sql_query("SELECT * FROM users WHERE emailAddress = '".$this->user."' AND password = '".$this->pass."' AND status = '1' LIMIT '1'"); $login = mysql_fetch_assoc($login); foreach ($login as $key => $value) { $sess[$key] = $value; } $sess['inTime'] = time(); $login = '1'; } return $login; } } ?> That is the main function, sql_query and sql_numrows is: <?php function sql_query($query = "", $transaction = FALSE) { unset($this->query_result); if ($query != "") { $this->num_queries++; if ($transation == BEGIN_TRANSACTION && !$this->in_transation) { $result = mysql_query("BEGIN", $this->db_connect_id); if (!$result) { return false; } $this->in_transaction = TRUE; } $this->query_result = mysql_query($query, $this->db_connect_id); } else { if ($transaction == END_TRANSACTION && $this->in_transaction ) { $result = mysql_query("COMMIT", $this->db_connect_id); } } if ($this->query_result) { unset($this->row[$this->query_result]); unset($this->rowset[$this->query_result]); if ($transaction == END_TRANSACTION && $this->in_transaction ) { $this->in_transaction = FALSE; if (!mysql_query("COMMIT", $this->db_connect_id)) { mysql_query("ROLLBACK", $this->db_connect_id); return false; } } return $this->query_result; } else { if ($this->in_transaction ) { mysql_query("ROLLBACK", $this->db_connect_id); $this->in_transaction = FALSE; } return false; } } function sql_numrows($query_id = 0) { if(!$query_id) { $query_id = $this->query_result; } return ($query_id) ? mysql_num_rows($query_id) : false; } ?> Any insight that can help to benefit these functions would be appreciated. |
