[PHP] niewbie - call methods from another class
Hello, I have something like this:
$stmt = $this->_dbh->prepare("INSERT INTO DOG (name_dog, race_dog, id_vet)
VALUES (?, ?, ?)");
$stmt->bindParam(1, $this->getNameDog() );
$stmt->bindParam(2, $this->getRaceDog());
$stmt->bindParam(3, );
$stmt->execute();
}
To make this insert function work, I need to fill the id_vet database column
with some values.
I cannot use $this->getIdVet() because this method is not in dog class, is
on the veterinary class.
So my question is:
How can I access the getIdVet() that is on the veterinary class to put it on
the insert dog method?
Thanks a lot,
Márcio
[PHP] self in inherited methods
Is it right that 'self' in inherited method still points to the parent? If it is, can you explain it? It makes me worry :) A piece of code below for example get_instance(); $c = $a->get_another_instance(); echo $a->get_name(),"\n"; echo get_class($b),"\n"; echo get_class($c),"\n"; ?> -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] How do I access a local variable?
Hi guys,
I have a function inside which I set alocal variable to store a result. Can I
access this variable in another function? if yes then how?
function tbl1($entrytitle, $entrytext)
{
global $conn;
$result= mysql_query("INSERT INTO tbl1(tbl1_id, title, text)
VALUES('NULL', '$entrytitle', '$entrytext')", $conn);
$tbl_id=mysql_insert_id($conn);// this is the local variable I'm setting
to get the last auto increment id
}
Now I wish to access that variable in another function thus:
function tbl2($name, $entrytitle, $entrytext)
{
global $conn;
$result =mysql_query("INSERT INTO tbl2(tbl1_id, name, title, text)
VALUES('$tbl1_id', '$name', '$entrytitle',
'$entrytext' )", $Conn);
}
Or is there a better way to store the variable?
Thanks in advance.

No, you can't. You either need to pass it back (recommended) or make it
global (not recommended).
function tbl1($entrytitle, $entrytext)
{
global $conn;
$result= mysql_query("INSERT INTO tbl1(tbl1_id, title, text)
VALUES('NULL', '$entrytitle', '$entrytext')", $conn);
$tbl_id=mysql_insert_id($conn);// this is the local variable I'm setting
to get the last auto increment id
return $tbl_id;
}
Now I wish to access that variable in another function thus:
function tbl2($name, $entrytitle, $entrytext)
{
$other_id = tbl1($entrytitle, $entrytext);
echo $other_id;
global $conn;
$result =mysql_query("INSERT INTO tbl2(tbl1_id, name, title, text)
VALUES('$tbl1_id', '$name', '$entrytitle', '$entrytext' )", $Conn);
}
PS : look up mysql_real_escape_string for when you save your data.

If a variable is local to a function, there is no way to access that
variable outside that function. You can pass it back as a return value
from the original function, or make it global (not advised) to make it
visible in other functions.

Where $date_reference is 2009-04-18 the following code gives me a day of

$previous_date = date('Y-m-d', $previous_date);

Slightly wrong syntax.
$previous_date = strtotime("$date_reference -1 days");

You need to read the strtotime page in the manual.
http://php.net/strtotime
It says that the second argument of the strtotime function is suppose to be a
unix time stamp.
Is the value that you gave us for $date_reference a unix time stamp? No
Your code should be like this.
// This converts 2009-04-19 00:00:00 into 1240099200
$date_reference_unix = strtotime($date_reference);
$previous_date = strtotime("-1 days", $date_reference_unix);
$previous_date = date('Y-m-d', $previous_date);
echo $previous_date; outputs 1969-12-30

What I do in this case is define it to unchecked in the php code and
then use the ternary operator to test it
$checkbox1 = 0;
$checkbox1 = (isset($_POST['check1'])) ? 1: 0 ;

The label tag should reference the input via the for attribute. Identifying
the input tag by id attribute value.
And using the for attribute of the label tag in conjunction with the id
attribute of the input tag, you can separate the label and form element
entirely, which is sueful if you still use tables to line up your
forms!

Or pass it by reference to the functions, so that both are able to make
changes to it.
