The above is my entire code.... the fist few blocks of php is all you need to look at. All I want to is to make sure that the person is trying to edit this post is the person that has posted it. otherwise, they need to be rerouted else wh开发者_如何学运维ere.
hmm... perhaps trying if ( intval($rows['userid']) == intva($currentusers))
Ok, you were using the wrong variable name. It is meant to by $currentuser not $currentusers.
if ( $rows['userid'] == $currentuser)
echo "true";
else
echo "false";
based on your variable name your $currentusers is an array of users, if so you can check if a value exists in it with in_array($value,$array);
if not, you have named your variable in a bad manner =D, maybe it's a type problem. cast both of them to int values with intval function
if(inval($rows['userid']) == intval($currentusers))
Nothing is wrong with your conditional statement, so it must be an issue with what is being stored in $currentusers and $rows['userid']. Can you provide more code specific to the values being assigned to those two variables?
EDIT: You have a typo in your code. You're comparing to "$currentusers" instead of "$currentuser". Try this:
if ( intval($rows['userid']) == intval($currentuser))
{echo "true";}
else
{echo "fasle";}
