 | Here is an example.

| | Re: else not working Technically, it doesn't matter if you have only 1 line statement after a condition. ie., [code] <?php $x = 1; if($x == 1) echo "$x is valid."; else echo "$x is invalid"; ?> [/code] This will not work if you have more than 2 statements in your condition. Btw, its …  |
| | [quote] Do not post homework problems expecting a quick answer without showing any effort yourself. [/quote] Seems like you didn't read the [url=http://www.daniweb.com/forums/faq.php?faq=daniweb_policies]member rules.[/url] Ch, ch. Read more on count and group by clauses. After reading them, you will be able to solve this query yourself. :) Good luck.  |
| | Very simple. [code] <html> <head> <script type="text/javascript"> function checkCheckbox() { var countselection = 0; var maximumselection = 2; var ch = document.getElementsByName('choice'); for(i=0;i< ch.length;i++) { if (ch[i].checked) { countselection++; } } for(i=0; i < ch.length;i++) { if (!ch[i].checked) { if(countselection == maximumselection) { ch[i].disabled=true; } else { ch[i].disabled=false; } } … |
| | I didn't go through so many functions in your script, but it works. You are supposed to select the options from the 2nd list before submitting. Unless you select them, they are not selected by default. |

| | Re: why ob_start() ob_start, as it indicates, will start output buffering. If you are using ob_start, then you should also use ob_end_flush, ie., flushing the output buffer. I have used ob_start at places when I had already echo-ed something [which was unavoidable at that time] before starting the session or calling the header … |
| | Not only echo, you will get this warning if you have session_start along with header function. Use [code] ob_start(); [/code] as the first line of your script to turn on output buffering and [code]ob_end_flush(); [/code] as the last line to flush the output to the buffer.  |
| | [QUOTE=leviathan185;1050970]you could also make a function out of it [CODE=php] <?php function arrayToString($array) { $string = ''; foreach($array as $value) { $string .= "{$string}, {$value} "; } return $string; } echo arrayToString($_POST['Prefered_Engineers']); ?> [/CODE][/QUOTE] Or simply, [code]$string = implode(",",$_POST['Prefered_Engineers']); [/code] |
| | To get a new line, you should add a <br /> to your echo. ie., [code] <?php echo $abbr['US']['MI']."<br />"; ?> //or simply <?php echo $abbr['US']['MI']; echo "<br />"; ?> [/code] [quote] Also, can you use the php include function in arrays like I used the HTML image function in … |
| | Re: Help Me Out!!! :) You forgot the column name as the 2nd parameter for mysql_result. [url]http://php.net/manual/en/function.mysql-result.php[/url] |
| | :( No. I pay around Rs. 1200 (approx $26) for my 512kbps connection. Its around Rs. 3000 for 1 mbps (that is approx $65). |
| | Re: Echo array You are supposed to put mysql_fetch_array in a while loop. [code] while( $data2 = mysql_fetch_array($query)) { echo $data2['firstname']; echo $data2['lastname']; echo $data2['task']; } [/code] |
| | Wow! This thread is unbelievable and you guys are mind blowing! :P  |
| | I don't recommend using mysql_fetch_row though. This will return an array with numeric indices and the script will fail if you add a new column to your table. I personally prefer using mysql_fetch_assoc . You can also use [icode] mysql_fetch_array($result,mysql_assoc) [/icode] to get the records based on its associative names. |
 | Re: auto refresh [QUOTE=network18;1049921] also do we need to use the exit() below it?Will it ever get executed when already redirected to the header-location page?No it will get its turn to execute.[/QUOTE] The exit function is used as a safety measure just in case the end user gets to echo something before header … |
| | There are still some typos. $GET_['formfield'] instead of $_GET['formfield']. One simple suggestion though. You don't need a switch/if-elseif-else condition to find out the day. A simple array will do it. This is what I am talking about. [code=php] <?php //nodag = Norwegian day //endag = English Day // dag = … |

| | Do as above. But, If you are a novice user and you find it hard to use ajax, then you can do the traditional way. Submit the form having an onchange event on all the dropdowns. When you select, say milk, from the first dropdown, submit the form, so $_REQUEST['firstdropdown'] … |

| | [QUOTE=leviathan185;1044621]It could be that you are using single quotes around the values that are meant to be integers, the single quotes are converting them to strings.

| | Hi, If I understand your question right, this should do the trick. [code] select * from customers c, cust_packages cp where c.cust_custnr = cp.cpack_usernr group by cpack_usernr having count( * ) =1 and cpack_canceldate != '0000-00-00' [/code] This will select all the customers with only 1 record in table cust_packages … |
| | One suggestion. When you are inserting a record to the table, you don't have to insert 'NULL' if its an auto increment field. Mysql will do it for you. Ie., [code] $orange_insert = "INSERT INTO orange (orange_name, orange_add) VALUES ('$val_name', '$val_add')"; [/code] Secondly, the 'error' you are getting is not … |

| | Hi, can you elaborate your question ? If you are inserting the value to the table from php, you can use [url=http://php.net/manual/en/function.substr.php] substr [/url] to insert only a part of a string. If you are directly inserting the record to the table, you can use mysql's [url=http://dev.mysql.com/doc/refman/5.0/en/string-functions.html#function_substr] substring [/url] function. … |
| | Hi, I am not sure how you are validating what mysql returns. In php, when you query the table, for example, [code] //query the table with username and password $query = "select * from table where username='test' and password='test'"; //execute the query and save the resource in $result. $result = … |
 | [url]http://www.tizag.com/mysqlTutorial/mysqlfetcharray.php[/url] You should use the array returned by mysql_fetch_array and not the result resource itself. ie., $row['content'], $row['name'] etc and not $result['title'] ! |

| | As I mentioned in another thread, have another variable array in the for loop, say, $cost_array. Assign the same value to it. Then do array_sum($cost_array). That will give you the sum of $cost. |
