So I am trying to display the value of a variable in a text box. The value is an integer.

 

So for example : $number1= 1+2;

 

the above is written between the php tags.

 

The following is found in the <form> tags:

 

<input type="text" name="number" id="number" value="<?php echo $number1; ?>" />

 

when I run the page the textbox is just empty. I have no idea what I am doing wrong. Any help???

The actual code:

 

This is not ALL of the code ... but the previous code is not important for this problem. This code is part of a function called MySlot()

 

if($reel1 != $reel2 && $reel1 != $reel3 && $reel2 != $reel3){

 

if(isset($_POST['submit'])){

$amount= $_POST['amount'];

$NoMatch = ($rand1/65 + $rand2/65 + $rand3/65)*$amount;

 

 

 

echo $rand1;

echo("space");

echo $NoMatch;

}

}

}

 

?>

</head>

<body>

<?php MySlot(); ?>

<form id="form1" name="form1" method="post" action="index2.php">

<table align="center" width="74%">

<tr>

<td width="100%" colspan="4" bgcolor="#28AD82">

<div align="center">

<input type="submit" id="submit" value="Spin!" name="submit">

</div>

</td>

</tr>

</table>

 

<table width="1005">

<tr align="center">

<td align="center">Amount bet:

  <input type="text" name="txt1" id="txt1" />

  </tr>

  <tr align="center">

  <td>You Win:

    <input type="text" name="txt2" id="txt2" value="<?php echo $NoMatch; ?>" />

    <input type="text" name="amount" id="amount" />

</td>

 

</tr>

</table>

</form>

</body>

</html>

try putting the variable in quotes, like below?

 

<? echo "$number1"; ?>

 

Variables do not need to be surrounded by quotes.

 

There is nothing visibly wrong with the code. Are you sure $NoMatch has a value?

the code for rand1 rand2 and rand 3 is not important .. I just simply want to display a variable value in a textbox... this value is an integer and it is the result of a calculation. I want to display this result in a textbox ... I tried " " and it still doesnt work

I'll guess you mean the php code that is setting the variable (leaving out relevant code almost always wastes time, same as posting a minimal example that has no resemblance to what the actual code is doing.)

 

If so, that variable does not exist outside of the function. You either need to return the value from the function or the code you are putting inside a function definition is actually your main program logic and does not belong inside a function.

Has anyone thought of the fact hes trying to use a string as an int?

 

if($reel1 != $reel2 && $reel1 != $reel3 && $reel2 != $reel3){

   if(isset($_POST['submit'])){
   if(is_numeric($_POST['amount']))
   {
      $amount= intval($_POST['amount']);   
      $NoMatch = ($rand1/65 + $rand2/65 + $rand3/65)*$amount;
    }

 

should work

PHP is smart (or stupid) enough to figure that out. The problem still remains that $NoMatch does not exist outside of the function.
