PHP - It Equals Zero But Im Still Getting An Echo?

OK, have no idea what's going on... I've done this a million times... why wont this output!??
I must have a major brain meltdown and dont know it yet!!!

Code: [Select]
<?php

// this echoes just fine:
echo $_POST['testfield'];


// but this wont echo:
echo 
if (isset($_POST['testfield']))
{
$_POST['testfield'] = $test;
}
echo $test;


/// or even this DOESNT echo either!:
$_POST['testfield'] = $test;
echo $test;

?>

Hi,

I have a page on my Intranet which lists a bunch of install files (for example, Microsoft Office), which are stored in the same directory structure as the site itself. I also have a duplicate installs folder structure in another office, on their local server. I want to make it so that the link changes, depending on which office the user is in. To simplify:

If (user is in London)
display London link
else
display Blackpool link

I've been trying to make it work via IP Address. The IP range in London is 10.44.6.* However, I can't make the script work with a wildcard (it works fine if I put a specific address in). The code I have so far is:

Code: [Select]
<?php
$ip=$_SERVER['REMOTE_ADDR'];
if ($ip == '10.44.6.*') {
?><a href="link1.php">Click Here</a><?php
} else {
?><a href="link2.php">Click Here</a><?php
};
?>
I think it may be an obvious solution, but if some kind person could perhaps point out my mistakes?

Thanks,
Dave

Hi All,

I'm trying to echo the response from an SLA query, the query works and returns the data when I test it on an SQL application.. but when I run it on my webpage it won't echo the result.

Please help?

<?php   
$mysqli = mysqli_connect("removed", "removed", "removed", "removed");  
$sql = "SELECT posts.message FROM posts INNER JOIN threads ON posts.pid=threads.firstpost WHERE threads.firstpost='1'";  
$result = mysqli_query($mysqli, $sql);   
echo {$result['message']}; 
?>

So I need to echo a row from my database with php, but where i need to echo is already inside an echo. This is my part of my code:


$con = mysql_connect("$host","$username","$password");
if (!$con)
  {
  die('Could not connect: ' . mysql_error());
  }

mysql_select_db("main", $con);

$result = mysql_query("SELECT * FROM Vendor");

while($row = mysql_fetch_array($result))
  {
//I need to echo right here  .................. but I get a blank page when I try this. Please Help.
  echo '<option value=$row['vendor_id']>'; echo $row['vendor_id']; echo '</option>';
  }

mysql_close($con);

Result: A Blank page.
Thanks in advance!

I have a log system that allows 10 logs on each side(Left and right). I am trying to make it so that the left side has the 10 most recent logs, then the right as the next 10. Any ideas?

Hi   I try to echo out random lines of a html file and want after submit password to whole content of the same html file. I have two Problems. 1st Problem When I echo out the random lines of the html file I don't get just the text but the code of the html file as well. I don't want that. I just want the text. How to do that?

for($x = 1;$x<=40;$x++) {
		$lines = file("$filename.html");
        echo $lines[rand(0, count($lines)-1)]."<br>";
        }

I tried instead of "file("$filename.html");" "readfile("$filename.html");" But then I get the random lines plus the whole content. Is there anything else I can use instead of file so that I get the random lines of text  without the html code?P.S file_get_contents doesn't work either have tried that one.     2nd Problem:   As you could see in my first problem I have a file called $filename.html. After I submit the value of a password I want the whole content. But it is like the program did forget what $filename.html is. How can I make the program remember what $filename.html is? Or with other words how to get the whole content of the html file?   My code:

if($_POST['submitPasswordIT']){
if ($_POST['passIT']== $password ){
$my_file = file_get_contents("$filename.html");
echo $my_file;
}
else{
echo "You entered wrong password";
}
}

If the password isn't correct I get: You entered wrong password. If the password is correct I get nothing. I probably need to create a path to the file "$filename.html", but I don't know exactly how to do that.   

Hi,
I have created a class "friendClass" and tried to echo it. It prints nothing without any errors, not sure what was it going on? Any helps would be appreciated!
Code: [Select]
        class friendClass{
           
                //attributes - variable
                public $name;
                public $sex;
                public $title;
                public $country;
               
                //methods - function
                public function eat(){}
                public function watch(){}
                public function drive(){}
                public function speak(){}   
               
            }
           
            $friend1 = new friendClass;
            $friend2 = new friendClass;
            $friend3 = new friendClass;
            $friend4 = new friendClass;
           
            $friend1 -> name = "Bach";
            $friend1 -> title = "Muscian";
            $friend1 -> sex = "Male";
            $friend1 -> country = "Germany";
           
            $friend1 -> eat("Bread");
            $friend1 -> speak("German");
            $friend1 -> drive("Horse");
            $friend1 -> watch("Beethoven");
           
            echo "Name is: ".$friend1->name;

What is the correct way to write an if/else statement within an echo? I need to alter this so that I can query to see what data is found and if not correct not to echo the rest of the statement.

Code: [Select]
echo '<td class="productbox">
<h1>' . $product_title . '</h1>
</td>';

So from the above code which is echoed within  the single quotes, what is the correct way to include an if else check on a value from the database.

I know how its done, but just want to save time and write it the correct way within this.

Hi freaks,
Yes im a noob...

I have some data in a db that im echoing out, but the last row wont multiply? The rest works great...
I have tried having the data as the following: 1.12 or 0.12 & I have tried having it as a var.

Do I need to have a % in there somewhere? Im adding up all the data then I want to multiply by 12% (*$row['markup'])


<?php echo $row['Stock1']*$row['qty']+$row['cutting']+$row['production']+$row['additional']+$row['pluscover']+$row['selfcover']*$row['markup'];?>

any help would be appreciated.

How do I echo the day from the db? It just displays day and I want it to display the day that was set.


<select name="date_of_birth" id="date_of_birth">
<option value="">Day</option>
<?php 

$isset = isset($_POST['date_of_birth']);

for($day = 1; $day <= 31; ++$day)
{
echo '<option';

if ($isset && $_POST['date_of_birth'] === $day)
{
echo ' selected="selected"';
}

echo ">${day}</option>\n\t\t\t\t\t\t";
}

?>
</select>

Hi Freaks, You guys helped me yesterday & now I have expanded on what I was doing & now need more help.

From my limited knowledge I'm trying to add theses strings together. (I'm a printer)

Its all adding up correctly until the end.

*$row['markup'] is only multiplying the last string and not the complete echo...I have indicated the last string in blue.

<?php echo ($row['laminating']*$row['qty'])+($row['Stock1']*$row['qty'])+($row['cutting']+$row['production']+$row['additional']+$row['pluscover']+$row['selfcover'])*$row['markup'];?>

What I need to do is add up everything in red and * by my markup value (12%) 
<?php echo ($row['laminating']*$row['qty'])+($row['Stock1']*$row['qty'])+($row['cutting']+$row['production']+$row['additional']+$row['pluscover']+$row['selfcover'])*$row['markup'];?>

any help would be appreciated!

I want to echo this div below but only if there is more than one of these fields missing.  How would I go about this?


<?php 

//only echo all of this if one or more of these fields does not exists so.......


if () {

   echo"

 <div id=\"items_todo\">
           <h3>Members Info</h3><br/>
         <ul>";

if (empty($User['address_L1'])) { echo "<li><a href=\"#\">Update Address</a></li>";} 

 elseif (empty($User['intro'])) {echo "<li><a href=\"#\">About You</a></li>";}

elseif (empty($User['profile_image'])){echo "<li><a href=\"#\">Add Profile Image</a></li>";}

elseif (empty($User['Nickname'])){echo "<li><a href=\"#\">Add A Nickname</a></li>";}
echo"</ul>

 </div>";
    } ?>

Hi all,

I have a page which simply pulls info from a database by id:
<?php
include ('connect.php');
$id = $_GET['id'];

$query = mysql_query("SELECT * FROM JOBS WHERE id=$id");
if (!$query) {
     echo "Could not run query: " . mysql_error();
     exit;
}
$row = mysql_fetch_row($query);
{
echo "<body><h3>" . $row[1]. "</h3>";
echo "<h4>" . $row[2] . "</h4>";
echo "<h4>" . $row[3] . "</h4>";
echo "<h5>Duties & Responsibilities:</h5><ul>";
echo "<li><strong>" . $row[4] . "</strong>" . $row[5] . "</li>";
echo "<li><strong>" . $row[6] . "</strong>" . $row[7] . "</li>";
echo "<li><strong>" . $row[8] . "</strong>" . $row[9] . "</li>";
echo "<li><strong>" . $row[10] . "</strong>" . $row[11] . "</li>";
}
?>

However in some cases the rows in the database may only contain data upto row 6 for example, how would I go about coding this so that it only displays rows that exist. If row 6 exists then 7 always will too as the information is connected. I am manually added this stuff into phpmyadmin as I do not need a form as once it is complete then it will not need to be added to.

Also row 8 and 9 may contain data but 6 and 7 may not

Many Thanks
