PHP - Turn Octal To Number?
Hi,
How would I do this, I'm trying to create a function to turn the octal (not sure whats its called exactly) input into its numberic representation, like so: <?php function octal_to_number($input) { //do something... return $number; } //would turn 0x17c into 380... echo octal_to_number('0x17c'); ?> Similar TutorialsHow do you turn off a php form after a set number of submissions? My form is not hooked up to a mysql database. Theoretically I think I would need to set something up that increments a number with each successful form submission. Then when the form hits a certain limit number like 300 it shuts off or hides the div that contains the form. Has anyone done something like this before? Any help or even just pointing me in the right direction is greately appreciated! I'm getting the dreaded " Invalid parameter number: number of bound variables does not match number of tokens" error and I've looked at this for days. Here is what my table looks like:
| id | int(4) | NO | PRI | NULL | auto_increment | | user_id | int(4) | NO | | NULL | | | recipient | varchar(30) | NO | | NULL | | | subject | varchar(25) | YES | | NULL | | | cc_email | varchar(30) | YES | | NULL | | | reply | varchar(20) | YES | | NULL | | | location | varchar(50) | YES | | NULL | | | stationery | varchar(40) | YES | | NULL | | | ink_color | varchar(12) | YES | | NULL | | | fontchosen | varchar(30) | YES | | NULL | | | message | varchar(500) | NO | | NULL | | | attachment | varchar(40) | YES | | NULL | | | messageDate | datetime | YES | | NULL |Here are my params:
$params = array(
':user_id' => $userid,
':recipient' => $this->message_vars['recipient'],
':subject' => $this->message_vars['subject'],
':cc_email' => $this->message_vars['cc_email'],
':reply' => $this->message_vars['reply'],
':location' => $this->message_vars['location'],
':stationery' => $this->message_vars['stationery'],
':ink_color' => $this->message_vars['ink_color'],
':fontchosen' => $this->message_vars['fontchosen'],
':message' => $messageInput,
':attachment' => $this->message_vars['attachment'],
':messageDate' => $date );
Here is my sql:
$sql = "INSERT INTO messages (user_id,recipient, subject, cc_email, reply, location,stationery, ink_color, fontchosen, message,attachment) VALUES( $userid, :recipient, :subject, :cc_email, :reply, :location, :stationery, :ink_color, :fontchosen, $messageInput, :attachment, $date);";
And lastly, here is how I am calling it:
$dbh = parent::$dbh;
$dbh->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_WARNING);
if (empty($dbh)) return false;
$stmt = $dbh->prepare($sql);
$stmt->execute($params) or die(print_r($stmt->errorInfo(), true));
if (!$stmt) { print_r($dbh->errorInfo()); }
I know my userid is valid and and the date is set above (I've echo'd these out to make sure). Since the id is auto_increment, I do not put that in my sql (though I've tried that too), nor in my params (tried that too). What am I missing? I feel certain it is something small, but I have spent days checking commas, semi-colons and spelling. Can anyone see what I'm doing wrong?
Hello,

$stmt = $this->db->mysqli->prepare($query);

Can you help me to solve this problem ?
Edited by danchi, 17 October 2014 - 10:25 AM. I need to display a number(the number is retrieved from the db) in the form input field such that only the last 4 digits is visbile, the remaining can be masked as * or X or whatever is applicable. I know the last 4 can be obtained as follows: Code: [Select] $number=substr($number,-4,4); But when i hit the submit button the form validates the input field and checks if the number is a valid number of a specific format. Therefore when I click on the submit button then I should still be able to unmask the masked numbers or do something similar that would help me validate the whole number. Code: [Select] <input type="text" name="no" value="<?php if(!empty($number)){ echo $number;} ?>"> Hi. I have made profile pages available for users.. How do I turn off <?php ?> for those pages?

Edited June 9, 2019 by HenryCanHello All, I'm trying to put a lot of what I do into function calls now to make my code a bit tidier and consise. Take this simple if statement: if ($_GET['thedate'] =='') { $var = date('l, jS F, Y',time()); } else { $var = date('l, jS F, Y', strtotime($_GET['thedate'])); } How could I put this into a function and in some kind of switch statement? Thanks I've tried to find an answer in the forum and although there have been posts similar I am unable to covert the answer to fit what I've got (mostly because I know very very little about php - sorry). What I need is one of the results to be added to the end of a url in order to create a link. Basically I have a storefront (www.storefront.com/) and the result NAME can be added onto the end of our url to create a link to the product page. (www.storefront.com/NAME) Code: [Select] <?php $dbhost = ""; $dbuser = ""; $dbpass = ""; $dbname = ""; //Connect to MySQL Server mysql_connect($dbhost, $dbuser, $dbpass); //Select Database mysql_select_db($dbname) or die(mysql_error()); // Retrieve data from Query String $price = $_GET['price']; $taxable = $_GET['taxable']; $weight = $_GET['weight']; // Escape User Input to help prevent SQL Injection $age = mysql_real_escape_string($price); $sex = mysql_real_escape_string($taxable); $wpm = mysql_real_escape_string($weight); //build query $query = "SELECT * FROM Products WHERE taxable = '$taxable'"; if(is_numeric($price)) $query .= " AND price <= $price"; if(is_numeric($weight)) $query .= " AND weight <= $weight"; //Execute query $qry_result = mysql_query($query) or die(mysql_error()); //Build Result String $display_string = "<table>"; $display_string .= "<tr>"; $display_string .= "<th>Name</th>"; $display_string .= "<th>Price</th>"; $display_string .= "<th>Taxable</th>"; $display_string .= "<th>Weight</th>"; $display_string .= "</tr>"; // Insert a new row in the table for each person returned while($row = mysql_fetch_array($qry_result)){ $display_string .= "<tr>"; $display_string .= "<td>'<a href="www.storefront.com/">' . $row[name] .

Thanks - and again, sorry for my lack of php knowledge. My web host wont turn on Curl.dll is there any other way to do this with out using Curl #---------------------------------------------------------------------------- # Curl code to store XML data from PWA in a variable #---------------------------------------------------------------------------- $ch = curl_init(); $timeout = 0; // set to zero for no timeout curl_setopt($ch, CURLOPT_URL, $file); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $timeout); curl_setopt($ch, CURLOPT_HTTPHEADER, array( 'Authorization: AuthSub token="' . $GDATA_TOKEN . '"' )); $addressData = curl_exec($ch); curl_close($ch); Say I have a chunk of code that looks like this (contains imagesx): Code: [Select] <span style="color: #0000BB">$width </span><span style="color: #007700">= </span><span style="color: #0000BB">imagesx</span><span style="color: #007700">(</span><span style="color: #0000BB">$img</span><span style="color: #007700">); <br /> within the code I would like to make all the php functions link to php.net I thought that the following code would work, but it does not, well because there is no spaces around the above word public function phpLinks($string){ $words = explode(" ", $string); $str = array(); foreach($words as $word){ if(function_exists($word)){ $str[] = preg_replace("/$word/i", '<a href="//php.net/'.strtolower($word).'">'.$word.'</a>', $word); }else{ $str[] = $word; } } return implode(" ", $str); } I now can not think of a good way to do this, so I am asking does anyone have any suggestions? Hello Everyone, I have a quick question for you all, I think its fairly simple... I have created a database and I am using PHP to grab the data: $usera = $_SESSION['username']; $query2 = "SELECT * FROM tracker WHERE id = '$usera', hidden = yes"; mysql_query($query2) or die('Error, query failed : ' . mysql_error()); This hopefully will return multiple rows which look like this in the database. id username date reps hidden 1 supremebeing 2011-01-02 30 yes 4 supremebeing 2011-04-02 46 yes How would i turn each result into a variable eg: $date1 = 2011-01-02; $date2 = 2011-04-02; $reps1 = 30; $reps2 = 46; I think i have explained that well enough for you to understand, please reply if not though and i will provide more information. Thanks in Advance I am trying to use a Wordpress module called WooCommerce PDF Invoices to make event tickets by modifying the layout of the invoice to create an online ticket to printout. I've successful reformatted the layout and it works like a charm except for one thing. The problem I have is that no matter what is bought the invoice reads "This is a ticket" which I hardcoded into the invoice design. What I would like is an if/then statement inserted into the invoice design that will print between "This is a ticket" or "This is a receipt" depending on if they purchase one of the 4 ticket items. "This is a recept" If ticket 1 then print "This is a ticket" else print "This is a receipt. If ticket 2 then print "This is a ticket" else print "This is a receipt. If ticket 3 then print "This is a ticket" else print "This is a receipt. If ticket 4 then print "This is a ticket" all else print "This is a receipt." I completely redesigned the woocommerce pdf invoice to look like an online ticket. The first half looks like an actual ticket.

I want to identify one of my 4 ticket items that may appear where the invoice prints the items and when one of them does appear it changes "This is a receipt" to "This is a ticket" in the first half. Is something like this possible? If so, can anyone give me a direction to find the coding for this? Can anybody give me an idea how to write this in php. I'm a pro at html but I've only taught myself how to modify existing php coding. I can't write it from scratch. Any help is appreciated.
Hi folks, If thought i finally managed to make a 2 player game with PHP and Jquery but i my whole computer gets stucked when the first player has gets his 2nd turn. What i basically have are 2 .txt files where both players units are listed. I will read this file into an array. Each unit has a speed key wich value increases when that unit has made an action, i write the new speed to the file and the script runs again. Heres the script that decides which unit goes first. Code: [Select] $time = 0; $found = 0; while ($found != 1) { foreach ($P1recruit as $p1) { if ($found == 1) break; if ($p1['speed']<$time) { $p1['speed'] = $p1['speed'] * ceil ($time / $p1['speed']); } elseif ($p1['speed']==$time) { $p1turn = true; $p2turn = false; $found ++; } } foreach ($P2recruit as $p2) { if ($found == 1) break; if ($p2['speed']<$time) { $p2['speed'] = $p2['speed'] * ceil ($time / $p2['speed']); } elseif ($p2['speed']==$time) { $p1turn = false; $p2turn = true; $found ++; } } $time ++; } Then follows all the HTML to build up the page. The player who has to act gets a form with choices to do with his unit. The other player gets "Opponents turn" in that window. So in the above code you see $p1turn or $p2turn gets true or false. This is for the Jquery script at the end of all the HTML to tell wich player needs to keep polling the unit files until theres a unit for him to act. Heres the script: Code: [Select] if ($p1turn == true) { if ($battle['player2'] == $_SESSION['SESS_MEMBER_ID']) { echo " <script type='text/javascript'> function turnlistener() { $('#main').load('battlegetnextunit.php'); }; $(function() { setInterval('turnlistener()', 5000 ); }); </script> "; } } if ($p2turn == true) { if ($battle['player1'] == $_SESSION['SESS_MEMBER_ID']) { echo " <script type='text/javascript'> function turnlistener() { $('#main').load('battlegetnextunit.php'); }; $(function() { setInterval('turnlistener()', 5000 ); }); </script> "; } } Now for the first player (the one who starts the battle) he can act properly. The next player can act, but he still is longpolling the .txt files as the form resets. If he acts withing the 5 seconds (setInterval('turnlistener()', 5000 )) the other player gets his turn again but my whole computer starts strugling and i'm not able to select anything in the form. Maybe it's like the players get double longpolling the 2nd turn. But i only have the last code once and obviously only 1 of 2 can run as either $p1turn or $p2turn can be true and it can only run for one player. What could this be? Is doing it this way even possible? I'm trying to figure this out for days now, i really hope someone can help me out. Thanks!
