PHP - using the "<" less than symbol will not parse

[rookers]

Hi
Is it me? Consider something noddy like this in PHP

Lets test if a number falls between a particular range:

$weight = 15;
$a = 10;
$b = 20;
If ($weight > $a AND $weight < $b)
{
echo "Success"
}

In the editor, text after the "<" symbol goes red and the function does not work. From all I have read on this, it should work. If I change the "<" to a "=" or a ">" it loses the red and appears to parse.
Does sellerdeck have an issue with using the "<" in PHP and if so why and what is the workaround.

Any ideas ?

Use && instead of AND. Also consider using brackets to make it clear what is being done.

The colouring is just SD getting confused. It thinks it's parsing HTML not PHP. It's a display issue only.

Hi there - many thanks for the reply. I have been at this all day and have tried every combination of &&, AND and brackets I can think of - nothing so far has worked. I also thought it was just a colouring issue, except that the "success" does not display.

Tried all these
If ($weight > $a AND $weight < $b)
If ($weight > $a && $weight < $b)
If (($weight > $a) AND ($weight < $b))
If (($weight > $a) && ($weight < $b))

You also had a missing ; at the end of the echo statement. This works correctly:

<actinic:block php="true">
$weight = 15;
$a = 10;
$b = 20;
if ( ($weight > $a) && ($weight < $b) )
  {
  echo "Success";
  }
</actinic:block>

And includes helper parentheses for those who don't understand operator precedence.
It is also a good idea to use lower case for PHP keywords. Use if instead of If.

Hi many thanks for that - I think the problem I am having is because I am actually trying to use the Sellerdeck field "shippingweight".
Consider this:

$x = "shippingweight"; (this is the inserted sellerdeck variable)

If I display $x I get 0.7 because that is the value I have in the "Weight in kg" field for the product. OK that is what I expected.

The problem is that $x is a text field, so when I do the compare operation in the posts above it does not work.
If I do (float)$x to convert to a floating point number, the result is 0.
I have tried all sorts of things to get $x to be a numeric field with 0.7 as it's contents with no luck.

Any ideas ?

ShippingWeight is always numeric so putting it inside quotes is unnecessary. Demo code that works here:

<actinic:block php="true">
$x = <actinic:variable name="ShippingWeight" selectable="false" />;  // treat as numeric / selectable="false" prevents errors in the Design Preview
echo ($x + 1); // demonstrate that we can do arithmetic with it
</actinic:block>

Best display the entire lump of PHP you are using as the problem may not be in the isolated snippets you post.

Great - I could not get it to work at all without the quotes, hence putting them in. But the selectable="false" has solved it. It does not put that in by default and I do not know how I would know to put it in. Anyway, it works now. Many thanks.
