timestamp

[up2trouble]

In mysql, I have a field defined as a time stamp. It is storing value
as 0000-00-00 00:00:00. It to store it in seconds.

<?PHP
$entered = mktime();
echo "<INPUT TYPE='text' NAME='$entered' VALUE='$entered' SIZE='13'
READONLY>";
?>

What am i doing wrong?

The TIMESTAMP data type has varying properties, depending on the MySQL
version and the SQL mode the server is running in. You should read the
following to understand it better. http://dev.mysql.com/doc/refman/5.0/en/datetime.html

OR

You can store $entered as LONGINTEGER, since mktime returns the result
as LONGINTEGER.

I changed it to bigint didn't see long one. Now it stores a 0. It
is not taking my value from mktime(). I read your suggested material.
I understood none of it.

I don't know if this helps, but I'm trying to print unique codes for
use in a db. The problem is that when I need more codes I only want
the new ones to print out not the ones that have been already
printed. I thought that I could just set a time and say to print
codes that were generated at a time greater than the time entered.
Instead of codes, I get: Query 2 failed cause: You have an error in
your SQL syntax; check the manual that corresponds to your MySQL
server version for the right syntax to use near '18:47:17' at line 1.

<?PHP
if(isset($_POST['printcodes']))
{
$gettime = date("Y-m-d H:i:s", mktime());
$sql= "SELECT * FROM $db_table10 WHERE entered < $gettime";
$result = mysql_query ($sql, $connect) OR DIE ('Query 2 failed cause:
' . mysql_error());
$num = mysql_num_rows($result);

echo "<FIELDSET><FONT SIZE='+1' COLOR='#FF0000'>These are your codes.
Just save to your desktop, then
open in Word to print.</FONT></FIELDSET";

while ($row = mysql_fetch_array ($result))
{
echo "<P STYLE='text-align: justify; width: 550px;'>This is the
anonymous id code which will allow you to take your end of class
survey.
You will need a new code for each class. ";
echo "Go to xxxxxxxxxxxx. Then click on the Survey link.";
echo "Your case sensitive code is :<BR>";
echo "<FONT SIZE='+1'><STRONG>{$row['id']}</STRONG></FONT></P>";
}
}
?>

Please learn how to reply properly. You were not responding to
yourself. Also, please quote the relevant parts (as in here).

As to your problem - you didn't give us enough information to go on -
like the real code you're using. Additionally, you need to determine
how you want the data stored - a unix timestamp works, but there are
valid reasons for using a datetime field, also (which is off topic in a
PHP newsgroup, and should be discussed in comp.databases.mysql).

I want a timestamp to store seconds and not a date/time format. The
only thing I took out of the code was the url for my page.

<?PHP
if(isset($_POST['printcodes']))
{
$gettime = date("Y-m-d H:i:s", mktime());
$sql= "SELECT * FROM $db_table10 WHERE created < $gettime";
$result = mysql_query ($sql, $connect) OR DIE ('Query 2 failed cause:
' . mysql_error());
$num = mysql_num_rows($result);

echo "<FIELDSET><FONT SIZE='+1' COLOR='#FF0000'>These are your codes.
Just save to your desktop, then
open in Word to print.</FONT></FIELDSET";

while ($row = mysql_fetch_array ($result))
{
echo "<P STYLE='text-align: justify; width: 550px;'>This is the
anonymous id code which will allow you to take your end of class
survey.
You will need a new code for each class. ";
echo "Go to xxxxxxxxxxxx. Then click on the Survey link.";
echo "Your case sensitive code is :<BR>";
echo "<FONT SIZE='+1'><STRONG>{$row['id']}</STRONG></FONT></P>";
}
}

?>

I should get a page of codes to print. It was working fine. However,
the problem is that when I need more codes I only want
the new ones to print out not the ones that have been already
printed. I thought that I could just set a time and say to print
codes that were generated at a time greater than the time entered.
Instead of codes, I get: Query 2 failed cause: You have an error in
your SQL syntax; check the manual that corresponds to your MySQL
server version for the right syntax to use near '18:47:17' at line 1.

When I create the code, I add in timestamp. I changed created to
entered and made varchar(25) in db. It doesn't keep a default value
and leaves what I entered in seconds.

$created = mktime();
$sql= "INSERT into $db_table10 (id, created) VALUES
('$random','$created')" ;

Reading documentation can save you a lot of headaches:

PHP answer:
<?php
list($usec, $sec) = explode(" ", microtime());
print $usec . "\n";
print $sec . "\n";
?>
RESULT:
Content-type: text/html
X-Powered-By: PHP/4.3.10

microsecond - 0.82285100
unix time in sec since epoch 1210823761

No, this is not a PHP answer, but given the proposed usage, it is a
better solution... and it works...

mysqlselect UNIX_TIMESTAMP(), from_unixtime( UNIX_TIMESTAMP());
+------------------+----------------------------------+
| UNIX_TIMESTAMP() | from_unixtime( UNIX_TIMESTAMP()) |
+------------------+----------------------------------+
| 1210822584 | 2008-05-14 22:36:24 |
+------------------+----------------------------------+

you can use it in an insert statement:

insert into table values (1,'test',unix_timestamp());
mysqlcreate table aa (a bigint);
Query OK, 0 rows affected (0.02 sec)

mysql>
mysqlinsert into aa values (unix_timestamp());
Query OK, 1 row affected (0.00 sec)

mysqlselect * from aa;
+------------+
| a |
+------------+
| 1210822778 |
+------------+
1 row in set (0.00 sec)

This was not the code in your first post - and you didn't have any code
in your second one. That is why I asked.

Your query fails because a datetime value needs to be in single quotes
in the query, i.e.

$sql= "SELECT * FROM $db_table10 WHERE created < '$gettime'";

And your other problems are SQL related - not PHP. I suggest you follow
up in comp.lang.mysql - which is where you should be asking
MySQL-related questions.
