Hello. Page gets id GET

$id = intval($_GET['itemid']);

This $ id in some pieces of code is visible in others is not visible. There are no functions on the page. Before the announcement, tried to do global, still not visible in some places. I read the manual and other sources, there is no reason for invisibility. For example, this simplest command is not executed:

 if($_POST['deleteitem']){ pg_query($dbconnect,"DELETE FROM items WHERE id = '$id'"); }

In single quotes, the variable must be included as follows: {$id} otherwise will not be processed. Read about the difference "and" in the documentation for php.

Better yet, bring the variable out of the string (string), for example:

 pg_query($dbconnect,"DELETE FROM items WHERE id = '".$id."'");
  • HELO WORD For example, after such a request, I display the product on the page: $ pic_query = pg_query ("SELECT * FROM items WHERE id = '$ id'"); $ pic_result = pg_fetch_assoc ($ pic_query); - recklessly
  • I have already tried it for everyone, and so ''. $ Id. "'And so {$ id} - rebukes
  • var_dump ($ id); before requesting? - iosp
  • iosp var_dump shows int310 - recklessly

    @iosp in the TS variable is in double quotes, if you have not noticed ... single quotes inside double quotes are not considered ... in a query in the database it would be framed just in quotes - Alexey Shimansky
