PHP - If Video Isnt Present Hide Player

I'm doing an ajax call from javascript using jquery library:

Code: [Select]

    ajaxCall: function(process, obj, type){     
        $.post("registration-post.php", type + "=" + process,
            function(data){
                if(data==""){
                    $(obj).css(registration.errorNotificationType, registration.validatedColour);
                }else{
                    $('.error').append($.trim(data) + "<br />");
                    $(obj).css(registration.errorNotificationType, registration.errorColour);
                    registration.progress = false;   
                }
            }
        );
    }


When the ajax calls the php page, I want the php page to know what post information the javascript has sent, rather than pre-defining what the PHP should be trying to retrive from the POST data.

Something like


          // pseudo

          $_POST["whateverwassentfromajax"]



I want to do this because I want to have one function doing everything. So in my javascript I am saying, check if the username and email have already been used...
But i dont want to call two different php functions.



//pseudo

function 1(){
      $_POST["username"];
}
function 2(){
      $_POST["email"];
}



Is there a special way to know which post data has been sent.
Or do i need to do a few if statements in php.

Hi guys,

I've got a line of code that asks for a column called "distance_completed" to be displayed as part of a string.

This column tells users how far people have run in a running race.

I set up this field in my database to 11,3 so all distances appear with a decimal at the end, and then 3 digits after the decimal place.

How would I alter the code so that the numbers that don't have any information in the places section just appear as integers Eg: 42 instead of 42.000 (for someone who ran exaclty 42km) and those that do have information in the decimal places appear correctly (eg: if a person ran 42km and 195m, it would appear as 42.195).

I think this is probably the only line of code that would need modification:

Code: [Select]

echo ($row['time'] != null)?$row["time"]:"dnf at ".$row["distance_completed"]."km.";

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.

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,

I have the following code in a WordPress theme which displays a companies website, Twitter and Facebook links.

What I am trying to do is display the text "Useful Links:" if one of the links exists, and hide the text if all are not present.

<p>Useful Links:</p>
<?php if ( $website = get_the_company_website() ) : ?>

                            <a class="company-website" href="<?php echo esc_url( $website ); ?>" itemprop="url" target="_blank" rel="nofollow"><?php _e('Website', 'jobseek'); ?></a>

                        <?php endif; ?>

                        <?php if ( get_the_company_twitter() ) : ?>

                            <a class="company-twitter" href="http://twitter.com/<?php echo get_the_company_twitter(); ?>"  target="_blank"><?php _e('Twitter', 'jobseek'); ?></a>

                        <?php endif; ?>

                        <?php
                        $facebook_link = get_post_meta( get_the_ID(), '_facebook_link', true );
                        if ( ! empty($facebook_link) ) : ?>
                            <a class="company-facebook" href="<?php echo $facebook_link; ?>"  target="_blank">Facebook</a>
   <?php endif; ?>

What would be the best way to show/hide the text depending on if the items are present or not?

Thanks

Hi all

I have a MySQL data base that is saving information from a form. One the form a user can add a business name which is text and a logo if they have one.

Now on my web page I want to beabe to display the picture if present if not I would like it to display the business name. How do I do this please. I know how to conect to DB etc just having problems getting my head around this problem.

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.

Hie,

hi friends,
I am using one API in which i need to make request for flight search, i am using soapclient to connect with the server to fetch available flights,

below is the xml in which request format will be.
SOAP 1.1

The following is a sample SOAP 1.1 request. The placeholders shown need to be replaced with actual values.

POST /tws_mind/Ws_TravelPortal.asmx HTTP/1.1
Host: 125.16.62.119
Content-Type: text/xml; charset=utf-8
Content-Length: length
SOAPAction: "http://tempuri.org/Ws_fnAirAvail"

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
  <soap:Body>
    <Ws_fnAirAvail xmlns="http://tempuri.org/">
      <objReq>
        <destination>

        <journeytype>string</journeytype>
        <Noofadults>int</Noofadults>

        <strPassword>string</strPassword>
      </objSecurity>
    </Ws_fnAirAvail>
  </soap:Body>
</soap:Envelope>

and below is the request which is made by me.
 $request=array( 'objReq'=>array('destination' => "DEL",
                                   'domestic' => 1,
                                   'journeydate'=>"25/10/2011",
                                   'journeytype'=>"R",
                                   'Noofadults'=>2,
                                   'Noofchild'=>0,
                                   'Noofinfant'=>0,
                                   'preferedairlines'=>"",
                                   'preferredclass'=>"Y",
                                   'returndate'=>"28/10/2011",
                                   'source'=>"BLR",
                                   'strPreferredCarrierType'=>"ANY",
                                   'GetCachedData'=>false
                                 )
                                         'objSecurity'=>array('strLoginId'=>"loginid",
                          'strPassword'=>"password"
                         )
             );
$wsdl="http://*/*/?wsdl";
try{
   $cliente=new SoapClient($wsdl);
   $vem=$cliente->Ws_fnAirAvail($request);
}
catch (Exception $e)
{
   echo $e->getMessage();
   exit;
}
          echo "<pre>";
          print_r($vem);

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. 

it worked before, although now $value consists of a space and i think it may be messing things up.

i pass a form field Code: [Select]
<input type="text" name="attributes[]" id="attributes[]">
and then i do this...

In the case above the 3 attributes[] passed are  "Value 1", "Value 2", "Value 3"


$attribute = "";
foreach($_POST['attributes'] as $key => $value)

{

$attribute .= $value . "/";

}
$atr = explode("/",$attribute);

#print_r($atr);

foreach($atr as $key => $value)

{
                            #THIS IS WHERE THE ISSUE ARISES... $_POST[$value] wont work

echo $_POST[$value] . "<BR>"; // DOES NOT WORK

#echo $value . "<BR>"; // WORKS -  shows "Value 1", etc....

#echo $_POST["VALUE 1"] . "--<BR>"; // DOESNT WORK EITHER

}



any ideas? im 90% certain if the $value variable was just "Value" and not "Value 1" it would work as it has before.

I am using an if statement. If the user has a credit value of 1 or more it echos a variable thats a form. When the user submits the form, it takes a credit away, so the credit value is -1. I need the form to dissapear, because the form has a button that will execute a query that I dont want to execute.

So, usually unset() fixes this, but its not in my case.

Heres the code
Code: [Select]
$a='<strong></strong>';
if ($hintcredit<1)
$a.='<font style="color: #cc0000;">You have already requested a hint! Once you guess the correct number, you will be able to get another hint. </font>';
else
$form= "<form action='blablabla' method='post'>blablablabla</form>";
$a.=$form;
$a.='<strong></strong>';
                        echo $a;
if ($_POST['request'] == "Retrieve Hint")
{
unset($form);
$form= '<b>One of the digits in your number is '.substr($num, -1).'</b>';
$newquery= "UPDATE userinfo SET hint_credits = '-1' WHERE username = '".$_SESSION['login_name']."'";
echo $form;

mysql_query($newquery,$link);

}
In this case, the form is still being shown.

I need the form completely removed after the form has been submitted.

This is simple and idk why its not working for me!?

Hi all, Ive had alot of problem with one script latly but I carnt see what it accually causing the problems.

Hi, I'm making a php game, and the image map isn't working. I don't know if it is a php or javascript issue, I don't think it is an html issue but I could be wrong so feel free to move this post. lol. But basically, The image map is supposed to link to an array of images. That is how the game works. There is the overworld image map, you click on a link, and go to the zone images, all in the same window. Any help GREATLY appreciated because having the image map feature work would be awesome finally. thanks. Derek.

here is the code that uses the image map. I cut out a lot of the unnecessary code , but the image map functionality related code is in there.


Code: [Select]
