PHP - Only Display Decimals If They're Present

Code: [Select]
$_POST['amount'] = intval($_POST['amount']);
if ($_POST['amount'] < 0){
message($lang_common['Bad request']);
}
if (!is_numeric($_POST['amount'])){
message($lang_common['Bad request']);
}
echo $pun_user['gold'];
echo '<br>';
echo $_POST['amount'];
exit;
if I enter 0.05
 in my gold input textbox and submit it, it reads 0, it doesn't read the decimal values, i need it to read them, but I also need it to be secure and use intval.. help

Hi,

I have a page on which decimal values are entered.
The problem is however that sql does not recognize the comma (the european decimal separator) as the decimal separator.
How can I change the input to something that sql can accept?
And what if someone enters a number in English format (a dot instead of a comma)? Or uses thousands-separators?
Has anyone have experience with this?

Hello All,
 
I have been wrestling with a regex for a couple of hours now and I finally had to give in and ask for help.  The weird thing is that it works if there are no new lines in the text, it fails if there is a new line(s) present.  
 
The code:

$matches = array();
$pattern = '~\[CUSTOM_TAG(.*?)\](.*?)\[/CUSTOM_TAG\]~';
preg_match_all($pattern, $html, $matches);
if (!empty($matches[0])){
foreach($matches[0] as $code){
$parameter = preg_replace($pattern, '$1', $code);
$content = preg_replace($pattern, '$2', $code);//get the content between the pattern
}//foreach($matches[0] as $code){
}else{
echo 'Match failed';
}//if (!empty($matches[0])){

 
So with that code in mind, if the $html variable (the text to be processed) is:

$html = '<h1>Hello, world!</h1><p style="color:#ff0000;">Some red text</p>';

A match is found.  
 
 
If the $html variable is:

$html = '<h1>Hello, world!</h1>
<p style="color:#ff0000;">Some red text</p>';

Match not found
 
Hopefully I'm just missing something simple in my regex.
 
Thanks in advance!

Hi, guys.

I want to present different ads to visitors in different countries.  For example, if a visitor is in Australia, I want him/her to see a different ad from, say, a visitor from the UK. Can this kind of thing be done with PHP? If so, will installing such a code slow down my site?

Any help will be appreciated very much.

Hi,

 

I have made a database linked with php that I use a html form for.

The HTML form requests a particular date to retrieve, and the php form it is linked to then retrieves data from the MySQL database from that date.

 

My question is: I want there to be a restriction so that the retrieval can only be for dates before the present date (and certainly not any date in the future).

 

e.g. if it is 6th July 2020, then the database can only retrieve from the 5th July 2020 and before. (7th July 2020 onwards also is not allowed.)

Is there a way I can do it? Anyone who can guide me to a particular code function or something of that sort - I would be deeply grateful as my searches have not come up fruitful.

Just looking to know if this is the proper way to implement this:

I need the below if to be true when any number between 100 and 1000 is the value of x, including say "105.55"

if($x>= 100 && $x <= 1000){
}


Basically I'm asking will a value of x with a decimal in it not cause the if statement to be true.

Hi - To me, this doesn't make sense.   My Order form uploads product weights in an array . If I echo out those weights they are fine ie 25.25

However, when I try to update the DB for some reason, the for loop strips out all but the first digit, so 25.25 becomes '2' or indeed if I had entered 9999999 it just '9' is entered in to the DB.

I have tried using number_format to pre-process the decimals, - but I get an error saying you can not use it in a write format.

Many Thanks to anyone who can help with this  !!


PS - I have abbreviated the below code for clarity:

Code: [Select]
$weight = $_POST['weight'];

        for ($i = 0; $i < $numloops ; $i++)

      {
       $sql ="
UPDATE `confirmedorder`
SET orderid = '$orderid[$i]', weight='$weight[$i]',status='finished', ordervalue='$ordervalue'
WHERE customerid = $customerid
";
$this->db->query($sql);
}

I want to find the first sentence in a string without counting decimals. Here is the code I have, but I still want it to display the decimals, but I don't want it to count as the end of a sentence.

$content = "This is my test string which is 3.5% of what I'm trying to do. This is only a test.";

Code: [Select]
function first_sentence($content)
 {
if(preg_match('/[0-9]+\.[0-9]/', $content, $num)) {
$number = "$num[0]";
$content = ereg_replace("$number","", $content);
}
preg_match('/^.*[^\s](\.|\?|\!)/U', $content, $match);
$string = $match[0];

$title_count = strlen($match[0]);
if($title_count > "6"){
return "$match[0]";
}
else {
$content2 = ereg_replace("$match[0]","", $content);
preg_match('/^.*[^\s](\.|\?|\!)/U', $content2, $step);
return "$match[0] $step[0]";
}}
Currently this is what it displays: This is my test string which is % of what I'm trying to do.
This is what I want it to display: This is my test string which is 3.5% of what I'm trying to do.

Hoping someone could help me with hiding a video player if a video is not present in the db. I have split up the code to make it easier to understand. Thanks in advance 






(int) $ListId=$_GET['ListID'];
  function mysql_resultTo2DAssocArray ( $result) {
$i=0;
$ret = array();
while ($row = mysql_fetch_assoc($result)) {
foreach ($row as $key => $value) {
$ret[$i][$key] = $value;
}
$i++;
}
return ($ret);

Hie,

Ok so say I have php do some calculations for me

Code: [Select]

$Value1 = 300;
$Value2 = 100000;
$FirstRatio = $Value1 / $Value2;

$Value3 = 8000;
$Value4 = 6000000;
$SecondRatio = $Value3 / $Value4;


$FirstRatio = 0.003
$SecondRatio = 0.0013

How would I go about doing these calculations and then sorting $FirstRatio and $SecondRatio and then it would take the highest ratio ($FirstRatio) and it would echo the value?

Hi there.

I am trying to display numbers if they have the numbers like:

number_format($price,2)

This gives us two decimal places i.e 7.23

Now thats fine, I would like to round the last two decimal places. I would like to make it 7.25, (rounding it from 7.23 to 7.25)

Similarly making:

12.44 to 12.45
33.18 to 33.20
52.13 to 52.15

So actually rounding the last two places. Coz obviously customers won't be able to pay 52 dollars 13 cents. So therefore rounding the last cent's (decimal part) making it to 52.15

Thank you.

All comments and feedback are welcomed.

My problem is i am getting below response, if i change the request in anyway i always get the same response.
Please correct my request in case i made bad request for the server.

stdClass Object
(
    [Ws_fnAirAvailResult] => stdClass Object
        (
            [objclsException] => stdClass Object
                (
                    [errorcode] => GEN0E0006
                    [errortype] => E
                    [errordesc] => Please provide Security object.
                )

            [strMessage] =>
        )

)

in my code below the **data is extracted correctly for the first foreach but doesn't return anything for 2nd foreach though selected one present inside the 2nd foreach** i still get the error Warning: Invalid argument supplied for foreach() for line `foreach ($authorlist as $post)`... however the 2nd foreach returns data correctly as soon as i remove the first foreach loop. 

I have written a bra calculator, when the user enters their measurements their bra size is displayed however as the code I have used to do this came from a help tutorial I do not understand how it was constructed as I am quite a newb.

The form works perfectly when returning data however if there is no size for a particular measurement it just displays nothing. I would like it to display N/A

I have tried adding various if elses but without success.

Any help is much appreciated

Code: [Select]
<FORM ACTION="<?php echo $_SERVER['PHP_SELF']; ?>" METHOD=get>
<input type="text" name="band" value="<?php echo $_GET['band']; ?>" />
<input type="text" name="bust" value="<?php echo $_GET['bust']; ?>" />

<INPUT TYPE=submit VALUE="Calculate">
</FORM>


<?php
$band = $_GET['band'];
$bust = $_GET['bust'];

$query = sprintf("SELECT size FROM bra_calculator  WHERE band='%s' AND bust='%s'", mysql_real_escape_string($band), mysql_real_escape_string($bust));
$result = mysql_query($query);

if (!$result) {
   echo "no";
}
else {
while ($row = mysql_fetch_assoc($result)) {
   echo $row['size'];
}
}
mysql_free_result($result);
?>
