Error Undefined Index
I keep getting the error: "Undefined index: page in ......." for this script:
<?
$page = $_Get["page"];
if (!$page){
$page = 1;
}
If the variable "page" isn't referenced in the url, I want it to be set to a default value of 1. This script works fine on one web server but not another. I'm assuming that it has to do with different php.ini files.

Undefined Index: Error
simple php website that displays a table from my mysql database. To prep for my MCSE I moved my home server to Windows 2003 Standard, I installed mysql and php 5 to run some of my databases and websites. Under Linux the site worked fine, under windows I keep getting Notice Undefined Index error on line 67 I have went back to the basics just pull the data then display and still get the same error. 60 $sql = "SELECT * from newschool ORDER BY State, CollNam"; 61 62 $result = mysql_query($sql, $dbcnx) or die(mysql_error()); 63 $number_of_rows = mysql_num_rows($result); 64 65 while ($newArray = mysql_fetch_array($result)) { 66 67 $id = $newArray['id']; 68 $testField = $newArray['testField']; 69 70 echo "The ID is $id and the text is $testField <br>";
Security Problem + Undefined Index Error
I am creating a simple message board for a project at school. Anyway, I have made the login page, so if the user is recognised, he/she enters the mainpage. The only problem I have is that, you can easily pass the variable user through the url and become a user if not already one, and ppl can pretend to be others. So, I was wondering, how do I prevent ppl from, if they enter the mainpage url, how do I write a message saying "Hacking Attempt" or something like that, so that I basically stop this security flaw. My 2nd problem is I have 4 boards for the msgboard. Each has url: mainpage.php?board=whatever The links work fine and the user can go to these links, but I get an error at the top of the mainpage saying "warning - undefined index 'board' " Here is the code:

Notice: Undefined index: name in F:uniSoftware engineeringassignment4guestbook.php on line 6 the variable $name is declared as $name = _POST["name"]; What could be causing this? I've recently installed php 5 on IIS with mysql 4. All running on windows XP downloaded code straight from my uni's tute site. went to run it and it sort of runs but I get these errors at the top of the page.

Reference the above thread: "Passing a HTML variable to a PHP file using include". One thing I've learned over the years is that an error doesn't always come from where the compiler/interperture says it does. Case in point maybe. I am getting this error: Notice: Undefined index: var1 in /var/www/vhosts/texasflyfishers.org/httpdocs/form.php on line 4 Warning: fwrite(): supplied argument is not a valid stream resource in /var/www/vhosts/texasflyfishers.org/httpdocs/form.php on line 5 Warning: fclose(): supplied argument is not a valid stream resource in /var/www/vhosts/texasflyfishers.org/httpdocs/form.php on line 6 in this function: <?php if($_GET["op"] == "ds") { foreach ($_GET["name"] as $key=>$value) { $fp=fopen($_GET["var1"],"a"); fwrite($fp,$_GET["name"][$key] ." ". $_GET["email"][$key] .." ". $_GET["phone"][$key] ." ". $_GET["id"][$key]); fclose($fp); } } ?> 'var1' comes from this last line in this snippet in a previous function: <html> <body> <?php include ($_GET["var2"]); ?// this works <br clear="all"> <?php include ($_GET["var1"]); ?//this works <form action="form.php?var1=>($_GET["var1"])" method="GET"// NOT I have found that the text editor you are using will color out the parts of code if they are correct. This code does not color out evenly. In the 2 'include' statements '$_GET' is red. In the 'form action' statement it is not. At this point 'var1' is a name on a disk with zero length. Is it possible that the error trapping of the 'include' function is taking care of this and the error trapping of the 'fopen' alerts you that it is going to crash fwrite because 'var1' is now corrupted?
Undefined Index
I have a simple search feature that searches 3 fields in 3 separate tables in a MySQL db, and I'm getting an 'undefined index' error, but only in the first section (first table)of the results. The undefined index is tied to the docs.projID in the "if ($row_search['docs.projID'] == 1)". This if statement is there to control to format of the link as pages are in different depths of subfolders depending on security needs. Googling this sort of error seems to reflect problems with the $_POST['keyword'] not existing when the results are first listed, so I moved the PHP results code from it's own page (search.php) to the main page, which didn't help. I have tried several different things and can't seem to get it working right. Here is what I have: Form: <form id="search" name="search" method="post" action="<?php echo $currentPage?>"> SEARCH<br /> <input name="keyword" type="text" size="20" value=""/> <input type="image" name="Submit" src="images/team_icon_go_btn.gif" /> </form> Results: <?php if (isset($_POST['search'])) { $keyword = $_POST['keyword']; mysql_select_db($database_website, $website); $query_search = "SELECT Distinct docURL, docTitle, docDesc, docs.projID, groupCode, projCode, catName FROM docs JOIN subcat on subcat.subcatID=docs.subcatID JOIN cat on cat.catID = subcat.catID JOIN groups on groups.groupID=proj.groupID JOIN proj on proj.projID=docs.projID WHERE proj.projID=docs.projID AND docURL LIKE '%$keyword%' OR docTitle LIKE '%$keyword%' OR docDesc LIKE '%$keyword%'"; $search = mysql_query($query_search, $website) or die(mysql_error()); $row_search = mysql_fetch_assoc($search); $totalRows_search = mysql_num_rows($search); $proj = $row_search['projCode']; ?> <?php if ($totalRows_search < 1) { echo "No internal documents matched your request."; } else {?> <p><table width=95%> <tr><td colspan="3"><font size="+1">Internal Documents:</font></td> </tr> <tr> <td><strongLink </strong></td> <td<strong>Description</strong></td> <td<strong>Project </strong></td> </tr> <?php do { ?> <tr> <td> <a href="<?php if ($row_search['docs.projID'] == 1) { echo $row_search['catName']."/".$row_search['docURL']; } else { echo $row_search['groupCode']."/".$row_search['projCode']."/".$row_search['catName']."/".$row_search['docURL']; ?>"><?php echo $row_search['docTitle']; } ?></a></td> <td><?php echo $row_search['docDesc']; ?></td><td><?php echo $row_search['projCode']; ?></td> </tr> <?php } while ($row_search = mysql_fetch_assoc($search)); ?> </table> <?php }?> </p> <?php mysql_select_db($database_website, $website); $query_search = "SELECT Distinct toolURL, toolName, toolDesc, tools.projID, projCode FROM tools JOIN proj on proj.projID=tools.projID WHERE toolURL LIKE '%$keyword%' OR toolName LIKE '%$keyword%' OR toolDesc LIKE '%$keyword%'"; $search = mysql_query($query_search, $website) or die(mysql_error()); $row_search = mysql_fetch_assoc($search); $totalRows_search = mysql_num_rows($search); ?> <?php if ($totalRows_search < 1) { echo "No tools matched your request."; }

Undefined Index Notices
I'm getting this: [client 192.168.5.50] PHP Notice: Undefined index: D1 in /var/www/html.....

Undefined Index From Name Search.
I am developing a Abstract Submission system for a small medical association. What they want it to do is be able to search an exsiting members database and fill out the information automagically from the search. The original database is in Access and I have successfully exported it into MySQL without any problems. When I do the search and all of the fields are in the database for the form that I want to have filled out it works perfectly. but... if one of the fields is empty. I get a error. "Warning: Undefined index: MiddleName ... on line x" for each of the fields that is empty. I know why this is doing it. But I don't know how to fix it. I was thinking of using if then statements and adding a space to the variable so that variable would not be empty but that would screw up my Error checking in the next step. Code:

Undefined Index Problem????
i have a html form called connect.html where i enter my username and password. After i have done that i hit the submit button. If i am successful, a message sayingUser [ w1009048] successfully connected which is in my handler1.php . I then click on a link called table which redirects me to another page (table.php) and SHOULD display the customer id and name from my customer table(database). When i click on the table link i get the following statmetents: Code:
PHP Notice: Undefined Index:
My question if more of a "good practice" type of thing. Let say I have a session variable $_SESSION['username']. And I want to display some text based upon the fact that this variable exists. So if I do this: <?php if ($_SESSION['username'] == 'bob@domain.com') { echo "Hello World"; } ?> When I do this, I get PHP Notice: Undefined index: username in my log messages. Now granted this is just a notice and not an error. So, my question is, is there anything wrong with this? Or is it really necessary to do checks like isset()??
Undefined Array Index Question
I am curious about how php deals with the following situation where I use an undefined index into an array. PHP seems to be behaving exactly how I want it to but I want to make sure that it is not a fluke. It seems like most programming languages would crash if you used an undefined index. Why does PHP work the way it does? My example is below ....
$http_post_vars (Warning: Undefined Index: 23232)
I have a form with one text box and when I submit the form and try and call the value on the next php page like this echo $HTTP_POST_VARS["myIP"]; I get the following error: Warning: Undefined index: 23232 in D:phpStatsdisplay_stats.php on line 6 however if I use the while loop to get the data from the form it works fine. Anyone know why this is happening?
Blank Page Caused By Undefined Index
I upgraded my php from 4.4.7 to 5.2.4 and now the entire website doesn't work. So I am trying to learn PHP and go through the site one error at a time. If you have a idea why the upgrade caused the site to fail that would be great. But in the meantime this is the problem i am stuck on. I get this error now when transferring to a page Notice - PHP Notice: Undefined index: REMOTE_ADDR in c:locationSession.php on line 45. That line has the following code. $GLOBALS["$SessionName"]=md5 (microtime() . $GLOBALS[REMOTE_ADDR"]); Like I said this code worked before the upgrade. Any idea what I can do to fix this problem?
[error]Undefined Offset,Use Of Undefined Constant
I have written a program for a long. However, when I placed it in other server, there are many error messages formed. For example: Notice: Use of undefined constant my_sort - assumed 'my_sort' on line 4 function my_sort( $row1, $row2 ) { return ( intval($row1[1]) > intval($row2[1]) )?-1:1; } usort( $str, my_sort);} I can't find out what's the mistake did I make. Would you know what's wrong in above scripting?
Supress Errors At The Page Level? Undefined Index Errors.
I'm creating a simple reply form, and if a form item isn't answered I get an error: "Notice: Undefined index: rb_amntspent in c:inetpubwwwrootmackinawsurvey.php on line 36" even if in the code I allow for an unselected item. (Code at the bottom here.) It works fine otherwise. Now in the past I've made a change to php.ini to repress errors, but for this project I don't have access to the php.ini. Is there a way to supress errors on that page for that session? Or, is there a way to just not get that error at all? Here's a sample of the code that gets the form response. If an item is selected, no error for that question, but if an item is not selected I get the error above even though I still get a successful echo for the "else" or "default" option which occurs if nothing is selected: $rb_visited = $_POST["rb_visited"]; //Have you ever visited Mackinaw City, Michigan? if ($rb_visited == "1") { $rb_visited_reply = "Yes"; } elseif ($rb_visited == "0") { $rb_visited_reply = "No"; } else { $rb_visited_reply = "You did not answer this question"; }; $rb_lastvisit = $_POST["rb_lastvisit"]; //When was your last visit to Mackinaw ity? switch ($rb_lastvisit) { case "1": $rb_lastvisit_reply = "Earlier this year (2003)"; break; case "2": $rb_lastvisit_reply = "Last year (2002)"; break; case "3": $rb_lastvisit_reply = "2 years ago (2001)"; break; case "4": $rb_lastvisit_reply = "3 years ago (2000)"; break; case "5": $rb_lastvisit_reply = "4 or more years ago (1999)"; break; default: $rb_lastvisit_reply = "You did not answer this uestion"; }
Error Message - 0 Is Not A MySQL Result Index
Could anyone explain what this might mean? Warning: 0 is not a MySQL result index I have a simple form set up where a user types in a keyword and then a page is displayed based on the keyword. See below: HTML page: <html> <head> <title></title> </head> <body> <form action="submitform.php3" method="GET"> <p><strong><font face="verdana, arial, ms sans serif" size="1">id#</font>:</strong> <input type="text" name="keyword" size="15" maxlength="25"> <input type="submit" value="Go!"> </p> </form> </body> </html> submitform.php3 page: <?php mysql_connect ("localhost", "username", "password"); mysql_select_db (dbname); $result=mysql_query("SELECT $url FROM table WHERE keyword LIKE '%$keyword%'"); list($url)=mysql_fetch_row($result); ?> The concept is really simple. A user types in an keyword and that page is displayed. There is a database set up with a table that has two columns. One is "keyword" and the other is "url" For example row 1 the keyword is abc, and the url is http://www.abc.com.
STRANGE "Fatal Error: Call To Undefined Function..." ERROR
why strange you ask? here goes: I have been working with Php and Mysql for a week without any problems. Today I tried executing a php page that connects to mysql and creates a new database, I got this error: "Fatal error: Call to undefined function mysql_connect() in C:Program FilesApache GroupApache2 est\_debug_tmp.php on line 3". I did some reading on the net and checked all my configuration, and it looks o.k. (and it already worked well a whole week before today). The strange thing is that I have another form that inserts data into the same database in Mysql, and it works like a charm (needless to say but both pages log in with the same username to the same database).

Also, I am using the ISAPI method for PHP instead of the CGI if it matters.

Tell me, why doesn't this work? $number = gmp_random("9999999999"); echo "$number"; gives me this: Fatal error: Call to undefined function: gmp_random() in /home/dpetersen/public_html/Site/newsletter.php on line 5 where line 5 is the line where the gmp_random() function is called. with or without quotes it doesn't work. And in the manual it says it will generate a random number between the number you specify and 0. but it doesn't give any examples and I just figured it would work like that.
