PHP if date equals then

Question

Hi I'm trying use a datepicker on a field I have. I'm trying to set the date field up so the user can only edit this field if the date value in the database is set to deafault (0000-00-00). If there is a value that's not equal to default I want to show the date created.

Here's the code I have attempted:

          if( $post['Date'] = var_dump(checkdate(00, 00, 0000))){ 
          echo "<input type=\"text\" class=\"datepicker\" name=\"pDate\" style=\"border:#000099; margin:10px;\" value=\"";
          echo $post['Date'];
          echo "\"> <input id=\"start_dt\" class=\"datepicker\">";
          }
          if( $post['Date'] != var_dump(checkdate(00, 00, 0000))){ 
          echo "<span>date created: </span>";
          echo $post['Date'];

          }

It's not working atm so any help or a point in the right direction would be great. Please also take into account I haven't added any proper styling so I'm only after help with the functionality.

Many thanks.

Don't use var_dump() in this way... var_dump() is a developers' debugging statement, not a method of displaying data to end users, nor of parsing values for if tests — Mark Baker

var_dump is for debug-outputting variables and does not return anything. So with $post['Date'] = var_dump(...) you are assigning null to $post['Date'] and null evaluates to false, so your condition is never met. — Basti

You don't want to use var_dump(). But it would help if you told us the structure of the value of $post['Date'].
You want to use ==, not = for your first if statement. You should be comparing, not assigning, (a) value(s).
The second if statement can just be changed to an else.
Just checking, but do you mean $_POST['Date'] rather than $post['Date']?

var_dump() is used for debugging purpose rather than inside conditional expression. Next, using = assigns the values not checks for them. You are assigning the values of var_dump() results to $post['Date'] So change them to ==

You should be trying to to something like this

  if( $post['Date'] == checkdate(00, 00, 0000)){ 
      echo "<input type=\"text\" class=\"datepicker\" name=\"pDate\" style=\"border:#000099; margin:10px;\" value=\"".$post['Date']"\">";
      echo "<input id=\"start_dt\" class=\"datepicker\">";
  } else {
      echo "<span>date created: </span>";
      echo $post['Date'];
  }

No need to invent anything: $post['Date'] == '0000-00-00'

Also, you should use NULL instead of default in most cases.
