PHP - Number Changing From 3,000.00 To 3.00
Hi
I'm using a form that uses number_format. It works fine until the number in question gets into the thousands. I can enter "3000", click Calculate and it comes back as "3,000.00" which is perfect. But if I click Calculate again, it changes to "3.00". How can I get it to remain "3,000.00"? Here's the code: Code: [Select] <form action="test.php" method="POST" > <?php if (empty($_POST['data1'])) { $number = ''; } else { str_replace(",","",$_POST['data1']); $number = number_format((double)$_POST['data1'],2); } ?> <input type="text" style="40" name="data1" value="<?php echo $number; ?>"> <input type="submit" name="submitCalc" value="Calculate" /><br /> <a href="test.php">Reset Form</a> </form> Similar TutorialsHello. I am working on something where I don't want to do this.... if ($pages <= 1){$P=1;} elseif ($pages > 1 && $pages <= 2){$P=2;} elseif ($pages > 2 && $pages <= 3){$P=3;} elseif ($pages > 3 && $pages <= 4){$P=4;} elseif ($pages > 4 && $pages <= 5){$P=5;} elseif ($pages > 5 && $pages <= 6){$P=6;} elseif ($pages > 6 && $pages <= 7){$P=7;} elseif ($pages > 7 && $pages <= 8){$P=8;} elseif ($pages > 8 && $pages <= 9){$P=9;} elseif ($pages > 9 && $pages <= 10){$P=10;} This could go on and on and I would rather use the for $ i++ for this so it will wright out the coding for as little or as much as it needs rather then I. However I am not sure how I would do this. I also have if ($PN == 1){$L = "0,20";} elseif ($PN == 2){$L = "20,20";} elseif ($PN == 3){$L = "40,20";} elseif ($PN == 4){$L = "60,20";} elseif ($PN == 5){$L = "80,20";} elseif ($PN == 6){$L = "100,20";} were I will need to be able to add 20 to the number. Is this easily done? I'm a bit loss tried a few things and its not working properly. 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,
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 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; As I am VERY new to PDO, can someone help me in converting the below 2 codes so that I can setup the testing site knowing at least this part works. Below is the old SQL that I need to convert but don't have to foggiest on where to start. If I can get some help with this I can slowly work through the rest of my site with a bit more ease.

Hi there, I need a PHP number format to match one and all of these sequence of numbers: 8500.00 9999.99 15.00 0.00 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! I have these numbers in an array: 14042 11130 10100 10100 9506 How can I add them all together? Was thinking about a while loop. Derp. >array_sum solved! One more question to ask. I'm trying to do a count of total logins that have happened in the last 5 months including the current one so far. My users_logins table has the following structu users_id, session_id, login_date(datetime), last_activity(datetime). What the end result is going to be is: <tr> <td></td> <th scope="col"><?php echo date("M", strtotime("-4 month")); ?></th> <th scope="col"><?php echo date("M", strtotime("-3 month")); ?></th> <th scope="col"><?php echo date("M", strtotime("-2 month")); ?></th> <th scope="col"><?php echo date("M", strtotime("-1 month")); ?></th> <th scope="col"><?php echo date("M"); ?></th> </tr> <tr> <th scope="row">Logins</th> <td>94</td> <td>53</td> <td>124</td> <td>92</td> <td>105</td> </tr> Where the first td would be May and the last td would be September. Do I have to do this in 4 separate queries. If so here's what I have for the first query. I'm not sure what woudl go for the WHERE. $four_months_ago_query = "SELCT COUNT(date_login) FROM users_logins WHERE ? "; Hello Everyone, i have developed one WAP application, i want to get MSISDN number of users who visit my site. My operator has also white listed my WAP application. I am getting MSISDN successfully on couple of Samsung Mobiles, but not getting same result on NOKIA, BLACKBERRY AND I PHONE or any other device. Please suggest me best way to get MSISDN number for all devices. Thanks, Nirav i wanted to choose 5 random numbers from 0-20. each number represents an index in an array. is there a way to pick out 5 random items from the array. say if random number generator piked a number 22, the last item in the array is at index 20, it wud then have to go to index 0. thanks! is there a way to make a random number input into mysql? like if i add a new customer to a table, i want to assign a random number to that customer. Hi all, I'm trying to build a simple shopping cart, there are only 8 products and I want to save the quantity value into a section for each product (product1, product2, etc). I'm having a problem where the I can't get the session value to increase by one if the same item is added to the cart again. Here is the code I have so far, am I missing something or is there a php setting that would cause this not to work.
<?php
session_start();
// setup
if(!isset($_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! <?php echo "How much money do you want landed on the account?!\n"; $landed = fgets(STDIN); $calc = ($landed * .25); $total = ($landed + $calc); echo "\nYou need to list the dummy for $".$total."...\n\n"; echo "Press enter to close this script..."; $exit = fgets(STDIN); ?> so say I enter 12000000000 which would make the $total .. $15000000000 how so I make the total have commas in it, like $15,000,000,000 Hi all I am trying to print a pattern shown below: 1 23 456 7891011 1213141516 17181920 212223 2425 26 Any know how to do it? I'm a bit stuck, I completed it with asterix. Hi. Im trying to make a PHP code that will find the average number. What I want is, a lot of input fields where you can write a number in. Then my code should take these numbers and divide them with the amount of input fields that has been written in. So that some fields you don't have to write a number, and the code will still give you a correct average. My code so far: Code: [Select] <?php if (isset($_POST['calc'])) { $m=$_POST['mat']; $e=$_POST['da']; $s=$_POST['eng']; $f=$_POST['fys']; $h=$_POST['bio']; $p=$_POST['geo']; $ave=($m+$e+$s+$f+$h+$p)/; } ?> <a href="" onclick="return hs.htmlExpand(this, { headingText: 'Beregn dit Gennemsnit:' })"> <b>Beregn dit Gennemsnit: <?php echo $ave;?></b><br></br> </a> <div class="highslide-maincontent"> <form id="gennemsnit" name="form1" method="post" action=""> Matematik<input name="math" type="text" id="mat" size="3" maxlength="4" /><br /> Dansk<input name="eng" type="text" id="da" size="3" maxlength="4" /><br /> Engelsk<input name="sci" type="text" id="eng" size="3" maxlength="4" /><br /> Fysik<input name="fil" type="text" id="fys" size="3" maxlength="4" /><br /> Biologi<input name="he" type="text" id="bio" size="3" maxlength="4" /><br /> Geografi<input name="pe" type="text" id="geo" size="3" maxlength="4" /></td><br /> <input name="calc" type="submit" id="calc" value="Beregn"/><br /><br /> </form> What I need is the code of how to divide with the amount of input fields that has been written in. thanks for any help hello, i am trying to see how i can pick a random number between 1-15 and exclude certain numbers. so i have a staff list that once a random number is created it inserts it into the staffnumber field. so the next time i create a random number for a staff, i want to make sure that the random number doesnt select an existing staffnumber. thanks! |
