php - echo $_GET['id'] not displaying anything -

i have page in user chooses recipe has unique id, sent page information recipe displayed not displaying anything.

$recipes = mysql_query("         select distinct `name`, `step1`, `step2`, `step3`, `image`, `reference`         `recipe` r         inner join `recipe_ingredients` ri         on r.id = ri.recipe_id         ri.ingredient_id in (".$ingredient1.",".$ingredient2.",".$ingredient3.")     "); 

this query on main page, allows user choose set of ingredients , retrieve recipes them.

echo '<form action="recipe.php?id=<?php echo $recipe_id;?>" method="post">';         echo '<input id="search" name="look" type="submit" value="look" >';         echo '</form>'; 

under each recipe there button user presses, send user specific recipe.

$sql = mysql_query("select `name`, `image` `recipe`  `id` = ".$_get['id']." limit 1"); 

this query i'm running on results page (recipe.php)

further down page ran this.

<?php echo $_get['id']; ?> 

it didn't display id , in url displayed this:

"recipe.php?id="

there data in table doing wrong?

the following echo syntax incorrect:

echo '<form action="recipe.php?id=<?php echo $recipe_id;?>" method="post">'; 

should be:

echo '<form action="recipe.php?id='.$recipe_id.'" method="post">'; 

i don't see setting $recipe_id, appears root of problem.

it unclear trying retrieve elusive $recipe_id from.

if trying pull in $recipes should include in sql statement:

select `id`,.... 

then pull in after $recipes->fetch_assoc():

$recipe_id = $recipes['id'];
