PHP - Simple Php Print Vs Echo Question.

Hey guys...I have a php that loads when the user is being taken after making a purchase.
On that php file, echo and print are disabled...and I need to send a variable from that php file to flash, doesnt matter is flash, could be other php file, html, anyway...


<param name="movie" value="retorno.swf?userId=<?php echo $Referencia; ?>" />


On the example above I am using echo $Referencia...I need some function to substitue echo/print...

Any ideas???

Thanks in advance!

Hi!
I wonder why this code is working:
for($i=0; $i<5; print $i++);
while this code:
for($i=0; $i<5; echo $i++);
gives the error
PHP Parse error:  syntax error, unexpected T_ECHO, expecting ')'
After spending some hours at php.net I learned that both calls ('echo' and 'print') are not real functions, but I wonder why they behave so different in the same context?!
Also 'tricks' like
for($i=0; $i<5; (echo $i), $i++);
do not work. Is 'echo' just forbidden in that particular case?

Best regards!

Ok so its been a while since school and ive forgotton most my php as Ive been more into site building wiht css, html and graphics...

<?php
$part=part("");
$size=size("");
$qty=qty("");
if (($part=="2") && ($size=="11") && ($qty=="100"))
echo "Price quote is $59.00"
else if (($part=="2") && ($size=="11") && ($qty=="500"))
echo "Price quote is $99.00"
?>


my goal is to have a simple form, wiht 3 drop downs qty, size, part are the field names. And depending what options they pick they get a price out put... im missing something so simple, I know it should only take a couple lines of code and simply repeat it wiht else if until you hit the end of all possible options.

Can some one please help?  Thanks

Hello!Can i echo data from 2 or more tables on the same page?

Hey guys,   I am using a function that echos out 10 images from my database.  I need to have a minimum of 4 echoed images.  Some categories have less than 4 images, so I would like to have a default image(s) echoed out if the database has 4 or less images.   Does anyone know how I can do this?   Below is the code I am using now to echo out the 10 images.   Thanks in advance:

 <?php 
		 
		 	 

                    $query = mysql_query('SELECT image_id FROM images ORDER BY RAND() LIMIT 10');

                    $i = 0;
					
					class myCounter3 implements Countable {
							public function count() {
								static $count = 0;
								return ++$count;
							}
						}
						
						$counter = new myCounter3;

                    while ($row = mysql_fetch_array($query))

                    {

                        if($i % 10 === 0)

                        {


                        }

                        echo	'<img src="http://www.mysite.com/'.$row['image_id'].'.jpg" width="300" height="auto"/>';
								
                        $i++;

                    }

                ?> 

Default Image: <img src="http://www.mysite.com/default.jpg" width="300" height="auto"/>

Hey people!

I've been setting a coding script for experience and this is my situation:

To buy a virtual flower, one needs to have 50 virtual coins.
So I first extract the number of coins the person has from the DB.
If the user doesn't have the sufficient number of coins, the BUY button will not be available and vice versa.

When the BUY button is clicked, I update the database, adding the flower to the user's inventory and subtracting 50 from the total number of coins the user has. This I do in that page itself using
if(isset($_POST['submit'])) 

Now, I need to know how I could check whether the user has at least 50 coins even if the button is available.
I hope that you could understand this.
I want to do it for validation purposes. Its to prevent the user spending the coins he has in another browser window and then returning to the visible button to click it.

I hope that I make sense. Thanks in advance!

Hi all - I am a novice when it comes to PHP, but I have managed to use it successfully many times. I have an issue where I can not get a variable to echo when I am calling it from within a file that is using SSI. Here is a basic example that should explain it better.

In the /index.php file:
Code: [Select]
<?php 
 $photo1="photo1.jpg";
 $photo2="photo2.jpg";
 ?>

<?php include('http://www.DOMAIN.com/includes/header.php'); ?>

In the /header.php file:

<img src="http://www.DOMAIN.com/photos/<?php echo $photo1; ?>">




When I try to echo $photo1 from within the /header.php file it simply does nothing, even though the variable is declared before the call for the include file.

If I try to do the echo with the IMG tag from within the /index.php file, it works no problem -but that wont work without a MAJOR site redesign with how things are configured.

Question is, why does this not work, and how can I fix it?

Huge thanks from this Newb!

I'm teaching myself php and mysql -- and my coding is a little rough.   But what i'm trying to do is display information from a mysql table in another table on a website.  I can do this just fine simply displaying the table, but i want a little something different.  I am only displaying one column of the table, instead of displaying it all in one column, i want to display the information in 5 columns.  for example.....  the table from mysql has names scott, john, james, mary, simon.  with the code I have i can make it display like this:
                                                                                         scott scott scott scott scott
                                                                                         john john john john john
                                                                                         james james james james james
                                                                                         mary mary mary mary mary
                                                                                         simon simon simon simon simon
i want it to diplay like this:
                                                                                          scott john james mary simon
                                                                                          new names will continue down

here is my code:

<?php

require ("connectigb.php");


$result = mysql_query ("SELECT pledgeName FROM pledgewall");

$fields_num = mysql_num_fields($result);


echo "<center> <h1>TSA It Gets Better Pledge Wall</h1>";
echo "<table border='1' align='center' style='width:960px;'><tr>";


while($row = mysql_fetch_row($result))
{
    echo "<tr>";

    // $row is array... foreach( .. ) puts every element
    // of $row to $cell variable
    foreach($row as $cell)
      if ($cell != "") {
for ($j=0; $j<5; $j++) {
        echo "<td>$cell</td>";
   }
   }

    echo "</tr>\n";

}
mysql_free_result($result);
echo "</table></center>";
?>

any ideas on what i can do here, i'm sure this is a simply fix.  i just haven't come across it yet.  thanks for the help in advance.

Hello everyone! I am a new user and I have a simple question. How do I set a password for a user to log in to my site with PHP? I have no MySQL database just a iOS code/host app. I know this isn’t secure but only me and my friends are on the site. Any help is appreciated. 

I can't figure out why im getting an error with this code.

if ($notif = mysql_query("SELECT * FROM notifications_1 WHERE recieverid='". $_SESSION['id']."' ORDER BY read ASC, id DESC") or die (mysql_error())); {

Code: [Select]
You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'read ASC, id DESC' at line 1

Hi guys, this function below is for card validation, however anycard i enter i get the invalid card number, this is not connected to any gateways, this is just an Luhn card validation demonstration.

<?php
  if ($_POST['pay'])
    {

$cardNo = addslashes(strip_tags($_POST['cardNo']));









function luhnCheck($cardNo) {
    $cardNo = str_replace(" ", "", trim($cardNo));
    if(!is_numeric($cardNo) or strlen($cardNo)>19) return false;
    $skip = $newNum = $total = 0;
    for($i=0;$i<=(strlen($cardNo)-1);$i++) {
        if($skip ==0) {
            $tmpNum = ($cardNo[$i]*2);
            $total += (strlen($tmpNum)==2 ? (substr($tmpNum, 0, 1)+substr($tmpNum, 1)) : $tmpNum);
            $skip = 1;
        }else{
            $total += $cardNo[$i];
            $skip = 0;
        }
    }
    return (($total % 10) == 0);
}

/* Example Usage */
if(luhnCheck($_GET['cc'])) {
    echo("Valid Number.");
}else{
    echo("Invalid Number.");
}





}





?>


<form name="confirm" method="post" action="">

<input type="text" name="cardNo">
 
                <input type="submit" name="pay" value="Pay Now">

I've seen this,
Code: [Select]
<?php } ?>
in a lot of scripts at the very end of the script. What does this piece of code do?

Hello there fellow programmers,

I was just wondering if there was any difference between doing this:

Code: [Select]
echo "Say Something Here";
and this

Code: [Select]
echo "Say ";
echo "Something ";
echo "Here";
Thank you in advance.

Notice: I am aware of the fact that they will output the same thing, my question is regarding resources.
