    Displaying results that have a space

    Hi there,

    Wondered if anyone could help, this may be more php side than SQL, im not sure, it involves them both.

    I have an SQL querie that is used to delete records from a database, it is as follows:

    Code:
    DELETE FROM categories WHERE category=$category
    The $category is generated from a drop down box (select/option in a HTML form) which is populated by a DISTINCT(category) statement.

    Now the only problem I have is that there is a record in the database called 'Plumbing & Heating' and when this record is selected the SQL statement trys to delete all records where the category=Plumbing and not the full Plumbing & Heating.

    Anyone else come across this problem and been able to resolve it?

    Thanks

    Any non-numeric literal value must be quoted within SQL:
    PHP Code:
    $query "DELETE FROM categories WHERE category='$category'"

    Hi there,

    Sorry, that was just me rushing to write this before I went to bed, the code is exactly as follows:

    Code:
    	$sqlquery = "DELETE FROM manufacturers WHERE manufacturer='$removemanufacturer'";
    But as mentioned, when $removemanufacturer result has a space (eg. Norwich Union) The SQL is looking to remove 'Norwich'

    Any ideas?

    Is the variable coming from a HTML form? If so, make sure you quoted the value in the form element, or it will ignore everything after the space.
    Code:
    <input type="text" name="foobar" value="<?php echo $value; ?>">
    It's best to just get in the habit of quoting all HTML element attribute values, as it is required for properly formatted XML and XHTML.
