PHP - Number Formats
I m printing the prices of the items in my db.
I want to print the prices like ; Price --- The format I want 75.000 --- 75 75.500 --- 75.5 100 --- 100 100.5 --- 100.5 1234.654 --- 1,234.654 1234.200 --- 1,234.2 1123456.789 --- 1,123,456.789 Simply I want to cancel the zeros after dot, and want to put comma every 3 digits before the dot. How can I do this ? Similar TutorialsI'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?
I am looking at using PHP (or whatever) to compress images/video/music when it is uploaded to be stored on the server and decompressed when required on the webpage. I know I will have to make a decompress function so it knows when to decompress to its full size, but any ideas on how to do the compression. Requirements: biggest, best and efficient compression of music/image/video files. Thanks in advance. Hi all I hope I have come to the right place. My system reads files stored on a drive and lists them to users through plain HTML, I made it 11 years ago and have to refresh my memory. My problem is that filenames seem to come in different formats, to how to decode/encode them is an issue...
My users use Scandinavian letters (æøåäöüõ) and it seems like one filename is in one format and another in another format. There is no logic to what format the filenames comes it. All files are ok and downloads as they should, they just dont list well. Any idea how I can handle this issue?
Dear all, is there any library that supports text extraction from docx,doc, excel, pdf, etc formats like Apache POI does on Java? Or should I port Apache POI classes to PHP code? best regards, ethereal1m Hello,
I have problem durring binding update query. I can't find what is causing problem.
public function Update(Entry $e)
{
try
{
$query = "update entry set string = $e->string,delimiter=$e->delimiter where entryid= $e->id";
$stmt = $this->db->mysqli->prepare($query);
$stmt->bind_param('ssi',$e->string,$e->delimiter,$e->id);
$stmt->close();
}
catch(Exception $ex)
{
print 'Error: ' .$ex->getMessage();
}
}
When I run function update I'm getting next error:Warning: mysqli_stmt::bind_param(): Number of variables doesn't match number of parameters in prepared statement
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 $number;} ?>"> Hey I have a string that looks like the following: Quote top-php-tutorials-2.html I have a script that cycles through each page. The 2 in the quote above is the page number. How can I extract the number between the - and the .html and replace it with another number? I've tried Code: [Select] substr($engine->selectedcaturl, 0,-6).$v.".html"But then I realised this only works for numbers that are 1 digit long Any input would be appreciated I have a calendar select date function for my form that returns the date in the calendar format for USA: 02/16/2012. I need to have this appear as is for the form and in the db for the 'record_date' column, but I need to format this date in mysql DATE format (2012-02-16) and submit it at the same time with another column name 'new_date' in the database in a hidden input field. Is there a way to do this possibly with a temporary table or something? Any ideas would be welcome. Doug hello, i have a start time and an end time (no dates). the following works great, except for when the start time is at night, and the end time is in the morning. im thinking if i can do an if the number is negative, add 24, that it will resolve my issue. any ideas? Code: [Select] $tbilled = $tfinish - $tstart; I am trying to create a registration form where users put their name, email and password only.
but i want to write an auto generated account number into database table for each user e.g; XY1234567 where XY should not change 1234567 auto generated random number and no duplicates (in numbers only).
example...
XY1234567
XY2345678
XY2233455
i found code
$num_of_ids = 10000; //Number of "ids" to generate.
$i = 0; //Loop counter.
$n = 0; //"id" number piece.
$l = "AAA"; //"id" letter piece.
while ($i <= $num_of_ids) {
$id = $l . sprintf("%04d", $n); //Create "id". Sprintf pads the number to make it 4 digits.
echo $id . "<br>"; //Print out the id.
if ($n == 9999) { //Once the number reaches 9999, increase the letter by one and reset number to 0.
$n = 0;
$l++;
}
$i++; $n++; //Letters can be incremented the same as numbers. Adding 1 to "AAA" prints out "AAB".
}
but its not working as i want. Any help please?
Edited by 684425, 27 December 2014 - 12:58 PM. Hey forum! I am currently developing a number search and I need some help creating a way to show similar results... For example if someone searches "2009" and there is no result for "2009" is there a way for me to query the database with "2007", "2008", "2010", "2011", etc. until I find a result? Any help would be greatly appreciated. I have to do an assignment for school where I create an html page and a separate page for php.

How can I test if a string has a number at the end? i.e. smith1 instead of smith? I won't know how long the string is or whether there is more than 1 number but I will know that the string's last character is a number. Thank you! Basically this gets a number from a table on my DB, and displays the content relevent to that number...the second part checks for that number and gets other information according to that number... what i want to do is make sure that the number from the first query exists in the table from the query, and if it doesn't print out and error saying "there is no information" or whatever.. anyone have an idea? hopefully this makes sense Code: [Select] <?php require_once('Connections/myConnect.php'); $detnum = $_GET['Details']; $detinfo = mysql_query("SELECT* FROM `Agency Stores - Table 1` WHERE F11=".$detnum); $det = mysql_fetch_array($detinfo); $salesnum = $det['F3']; $salesinfo = mysql_query("SELECT* FROM `By Agency Store _` WHERE store_store=".$salesnum); $sales = mysql_fetch_array($salesinfo); if(mysql_query("SELECT* FROM `By Agency Store _` WHERE store_store=".$salesnum)){ } ?> Hi all, i have this records that coming from the database: 0 0 0 1 1 1 1 1 0 0 1 1 1 1 1 1 i want to build a loop that will do like that: if ($res==0) {$res11==number} if ($res was allready 0 ignore it) if ($res==1 ignore it and all other $res=1 and wait till it's $res=0 again if ($res==0 again) { $res11==newnumber } please guide me to doing that, im stuck! thanks Hello Everyone, i have developed one WAP application, i want to get MSISDN number of users who visit my site. My operator has also white listed my WAP application. I am getting MSISDN successfully on couple of Samsung Mobiles, but not getting same result on NOKIA, BLACKBERRY AND I PHONE or any other device. Please suggest me best way to get MSISDN number for all devices. Thanks, Nirav Hi Guys I have a code what inserts very simple queries to database, im trying to add a random reference number for each enrty using $reference = rand(111111111111,999999999999); but each time I add an entry it gives me the same random number previously generated for previous entry can you help pleasE? I am getting the result I expected with ORDER BY/GROUP BY queries WITH a troubling EXCEPTION: the data is being IN ORDER from 0 thru 9, but 10 (which in this test sample is my LARGEST quantity) is being inserted between the ONE and 2 quantity. Not sure if this will occur with ALL teen values, as well as hundreds. The column is a SMALLINT field (not sure if that makes a difference)> Is there a solution for this situation? Hi all, I'm trying to build a simple shopping cart, there are only 8 products and I want to save the quantity value into a section for each product (product1, product2, etc). I'm having a problem where the I can't get the session value to increase by one if the same item is added to the cart again. Here is the code I have so far, am I missing something or is there a php setting that would cause this not to work.
<?php
session_start();
// setup
if(!isset($_SESSION['product1']))
$_SESSION['product1'] = 0;
if(!isset($_SESSION['product2']))
$_SESSION['product2'] = 0;
if(!isset($_SESSION['product3']))
$_SESSION['product3'] = 0;
if(!isset($_SESSION['product4']))
$_SESSION['product4'] = 0;
if(!isset($_SESSION['product5']))
$_SESSION['product5'] = 0;
if(!isset($_SESSION['product6']))
$_SESSION['product6'] = 0;
if(!isset($_SESSION['product7']))
$_SESSION['product7'] = 0;
if(!isset($_SESSION['product8']))
$_SESSION['product8'] = 0;
// add product
if(mysql_escape_string($_GET['add']) != '') {
$addItem = mysql_escape_string($_GET['add']);
$_SESSION["product$addItem"] = $_SESSION["product$addItem"] + 1;
}
echo "product$addItem = ".$_SESSION["product$addItem"];
?>
Thanks! |
