I have an input form to create a customField name, when the page loads the textbox is automatically filled with "cst_".
I preset this value in my class:
class customField{
// DEFINE PROPERTIES
public $id = 0;
public $groupId;
public $name = 'cst_';
public $displayName;
public $type;
public $defaultValue;
public $required;
public $orderCount;
...
When I go to save the fields on my page, I check to make sure that the user has imputed more values than just leaving the "cst_"
I do this by simply:
// CHECK FOR ONLY "cst_"
if(strlen($customField->name > 4)){
// SAVE
$customField->save();
}else{ noticeSet(1,'PLEASE ADD NAME');noticeSet(1,strlen($customField->name));}
in my textbox I added cst_water hardness however I get the error
PLEASE ADD NAME
18
I don't understand how it is failing at that if statement
I've added a noticeSet before the if statement and it shows 18.
Is there any better way to see if a user has added more than just "cst_"?
You have a parentheses out of place so you end up with ($customField->name > 4) which results in false. So the expression ends up if(strlen(false)) which is obviously no good. Fix it with:
if(strlen($customField->name) > 4){
If cst_ must be present, then maybe:
if(strpos($customField->name, 'cst_') === 0 && strlen($customField->name) > 4){
Or shorter but probably slower:
if(preg_match('/cst_.+/', $customField->name)) {
Does your $customField->name contain the name? Is that checked? If so, i can see a problem in your code. You use:
if(strlen($customField->name > 4)){ ...
It should be:
if(strlen($customField->name) > 4){ ...
Anyway, this just will check that the name length is greater than 4. It won't check if it is "cst_".
Instead, you should be doing something like:
if (isset($customField->name) && $customField->name != "cst_") {
//Your code
}
The statement should read
if(strlen($customField->name) > 4){
(note the moved bracket)
Ideally, though, you want
if ($customField->name != "cst_") {
