[PHP] Re: NULL Date Entries...

In one of my forms, I am building a variable that I can use as an

On my form, I have several DATE fields which exist of 3 fields MM - DD

when I build my string it looks like this:
array('dbf'='applicant_dob',
'f'=array('applicant_dob_1','applicant_dob_2','applicant_dob_3'),
'req'=0, 's'='/'),
This enters in the DB fine when there is a DATE, but when these fields
are left empty, it inserts into the the DB as 2069-12-31.
How does one deal with this?
Don Wieland
Aside from all the good advice already offered, if you want to accept a null
date, check what your DB does with it and whether you can set a default for
an empty date. Mysql for example can use -00-00

Robin, I think you hit it exactly on the head with the quote issue.
Steve, use regular single or double quotes, not any kind of fancy
quotes or backticks. It may be the editor you're using: if you use
Microsoft Word or another similar word processor, it may replace the
quotes with something it things is prettier. If you're using
Windows, use notepad, `edit.com` from the command line, or download
any IDE you'd like - many or which are free and open source, and even
handle PHP specifically.

[PHP] rtrim Null characters
So, for fun, (well, *MY* idea of fun) I implemented a dirt-simple CAPTCHA. The image is totally OCR-able, but anybody wants to work that hard at it can have at it. That's modular enough to (really) fix later anyway/ After lots of encryption/decryption with urlencoding, htmlentities, and base64_encoding, to keep all the data kosher over HTTP et al... I end up with a string with a bunch of NUL characters (ord($char) == 0) tacked on the end, but otherwise correctly decoded. I'm not really sure if it's base64 or the encryption itself that pads the string, and don't really care, to tell you the truth... Anyway, my question is, what is the morally correct function to use to remove these null characters from the end of my string? I'm guessing 'rtrim' would work, but is a NUL char really whitespace? I suppose I could do str_replace(), but if things go bad some day, I don't want to confuse myself by removing NUL characters in the middle of the messed up string. A second related question: Given that the string to be encrypted is a single word and thus very short, the PHP manual makes it quite clear that encrypt_mode of ECB is the right choice. YAY! What is not readily apparent, and what I can't figure out from my research is if any of the algorithms available is better suited to this usage. To be clear: I'm mcrypt_encrypt()ing the secret word into the URL and a hidden form element, along with the IV, ditto, and so both are available to the potentical malicious user. So if exposure of IV is an issue in any suggested answer, keep that in mind. The following options are available in my webhost's install: cast-128 gost rijndael-128 twofish arcfour cast-256 loki97 rijndael-192 saferplus wake blowfish-compat des rijndael-256 serpent xtea blowfish enigma rc2 tripledes We can safely eliminate any hypothetical best which is not in that list. -- Like Music? http://l-i-e.com/artists.htm -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

[PHP] Inserting NULL Integer Values
Hi,
Up to this point in time I used to construct my insert statements like this
$qid = mysql_query('INSERT INTO MYTABLE (
column1,
column2,
) VALUES (
'.$value1.',
'.$value2.'
)');
However I understand it is better to remove the quote marks around an insert
if the column type is an integer. This is easy to do, however if the $value
is empty it causes a mysql error. Has anyone encountered this and found a
solution?
Thanks for your advice

This can not be right, can it? I have never heard of such a thing. As

So how can it equal 0?

In C the NULL macro is equal to 0. In PHP null is equivalent to 0. The
test will fail if you use === instead.

reposted on this list as requested, an initial reply is include: Original Message Delivered-To: [EMAIL PROTECTED] To make matters worse, $x[5] = NULL; causes array_key_exists to return true for 5 even though isset($x[5]) is false and even worse, unset is the function you use to remove 5/NULL from the array. So... you have to unset something for which isset is false!

[PHP] assigning NULL to a variable
how would you assign NULL to a variable if its original value is ? otherwise leave
it with its value...
the form im working on has a date field called date on the form itself. that date
will get turned into $_SESSION[add][date] on the next page...
i want it so if the person filling out the form didnt leave a date (left date field
blank) then it should be NULL so the mysql table will insert the current date...
so far i have this code:
if(empty($_SESSION['add']['date'])){
$_SESSION['add']['date']=NULL//or should it = FALSE??
}
//if its already filled do nothing else to it
is there a better way to do this than this way?

You may also want to start using $_POST, $_GET, or $_REQUEST as they're

You may want to look into using the superglobal $_SESSION instead of

[PHP] ldap_add() - null values in fields produce an value #0 invalid per syntax error on ldap server
Hi,
New to the list and hoping someone might be able to help me.
I have been using PHP scripts that are to maintain a company address book
with a lot of data about contacts, both inside and outside the company. The
scripts, which are generating html pages and reading input values back in,
have been working fine with PHP 4.2.1 as a library module for apache 1.3.26
and openldap 1.2.13. However, openldap 2.0.23 and 25 have been generating
errors with these same PHP scripts, specifically in the ldap_add() and
ldap_modify() functions.
The problem comes when fields in the html pages are left empty, which is
normal for this application. For those familiar with the ldap_add/modify
functions in PHP, the array that is passed in has some values, say for
example title, fax, mobile, ... left empty, and therefore NULL (I have
checked, they really are NULL's stored in the array). When the values make
it to the ldap server however, they appear to be no longer NULL's, but a
#0, and through debugging output on the ldap server, I have seen it is
generating an invalid per syntax error.
The ldap servers have been complied from source and installed on a SuSE linux
professional 7.3 system. Hardware resources are no problem (640Mb RAM, 2Gb
swap, 800Mhz processor, 130Gb HDD space with 6Gb free on the working
partition with this stuff)
Does anyone have any suggestions as to how I can address this problem. It
is important that null values can make it into the ldap server as putting in
other values to try to work around the problem will mess up other
applications that use the ldap server, as will not inserting the fields into
the ldap server.
Ian
The following code segment demonstrates the problem:
?php
$ds=ldap_connect(localhost); // The LDAP server is on this host
if ($ds) {
// bind with appropriate dn to give update access
$r=ldap_bind($ds,cn=ShnetAdmin, o=shnetdemo, thepassword);
// prepare data
$info[cn]=John Jones;
$info[sn]=Jones;
$info[mail]=; // - NULL VALUE HERE
// The following lines also produce the same result...
//$info[mail]=NULL; // --- NULL value here
//$info[mail]=\0; // --- NULL value here
//$info[mail]; // --- NULL value here
$info[objectclass]=person;
// add data to directory
$r=ldap_add($ds, cn=ShnetAdmin, o=shnetdemo, $info);
ldap_close($ds);
} else {
echo Unable to connect to LDAP server;
}
?
Which produces the following segment of debugging output on the ldap server,
started with slapd -d 255.
dn2entry_r: dn: CN=SHNETADMIN,O=SHNETDEMO
= dn2id( CN=SHNETADMIN,O=SHNETDEMO )

Re: [PHP] Re: NULL value for variable
It seems that you use global where it is not needed- outside of any function First error because error_reporting is not set to 0 in php.ini so error_reporting valus includes E_WARNING. if you set error_reporting=0 in php.ini or error_reporting(0); in the script you will not receive the first warning but probably lose the second which is useful.

I would try:
if (isset($fieldname) empty($fieldname)){
// do something here with the variable
} else {
$fieldname="na";
} // if (isset($fieldname) empty($fieldname))

Subject: [PHP] check null value
If I have one input text box that when it is submitted to next page, I want
to check first if it is nothing, then write "na" on next page, else just
echo whatever it is, is it correct to do this?
if ($fieldname == ""){
$fieldname ="na";
}
...
(then come to the html bit below)
td?php echo $fieldname ?/td
I wonder specificly about the check if it is null part if it is corerct. Any
thoughts?
