switch statement and loop not working

[Ruth]

for($rating_num; $rating_num <= 5; $rating_num++)

{

switch($rating)

{

case 'star':

echo '<img src = "images/star.gif">';

break;

 

}

}

 

I have a drop down box that will give a numeric rating($rating_num) 1-5. When I select 5 it will display 1 start, when I select 1 it will display 5 starts. It seems to be running backward. Any ideas on how to fix this? $rating is the way the user wishes to display the rating stars, thumbs up, or numeric.

for($rating_num = 1; $rating_num <= 5; $rating_num++)

{

  switch($rating)

  {

      case 'star':

        echo '<img src = "images/star.gif">';

        break;

       

  }

}

the use of a switch on a single condition is pretty pointless

try

<?php
for($rating_number = 1; $rating_num <= 5; $rating_num++}
if($rating[$rating_number] == "star"){
echo "<img src=\"images/star.gif\"  alt=\"star\" />";
}
else{
#echo No star img
}
}
?>

for($rating_num = 1; $rating_num <= 5; $rating_num++)

{

  switch($rating)

  {

      case 'star':

        echo '<img src = "images/star.gif">';

        break;

       

  }

}

 

I tired this and no matter which number I select I get 5 stars. I've also tired $rating_num = 0 and get the same result

There will be more then one condition I'm just trying to get this one to work before I start adding more.

[cooldude832]

well of course u get 5 stars or no stars

the var $rating isn't defined in what we see so if it is "star" it will always be true

you need to show more code

[Ruth]

Here is my entire code

 

$movie = $_POST['movie'];

$rating = $_POST['rating'];

$rating_num = $_POST['rating_num'];

$comment = $_POST['comments'];

 

echo "Move: $movie <br />";

 

for($rating_num=1; $rating_num <= 5; $rating_num++)

{

switch($rating)

{

case 'star':

echo '<img src = "images/star.gif">';

break;

 

}

}

 

The rating is being defined in the post

[Ruth]

Forgot to take out a suggestion I tired here is my orginal code

 

<?php

$movie = $_POST['movie'];

$rating = $_POST['rating'];

$rating_num = $_POST['rating_num'];

$comment = $_POST['comments'];

 

echo "Move: $movie <br />";

 

for($rating_num; $rating_num <= 5; $rating_num++)

{

switch($rating)

{

case 'star':

echo '<img src = "images/star.gif">';

break;

 

}

}

 

?>

Is anyone still out there? No matter where I look nothing has a good suggestion for how to get this to work correctly.

Your for statement does not make sense. It should be:

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

 

I presume rating_num determines how many stars are shown.

[Ruth]

Your wonderful I didn't know you could use $i by itself I thought you had to set it to something. Very cool thanks so much.

 

 

[wildteen88]

Umm, $i is set to 0

for($i=0; ... )

 

You may need to read up on how a for loop works.
