PHP - If Value = 0 Ignore
Hi all,
I have a simple html form, when the values are posted to the php page I want to be able to bring up particular products based on specific details. However if the user does not enter a value, I want the script below to ignore that particular field and show all the results not taking in to consideration that field. Hope you understand. I was thinking maybe I could use something like if $_POST == "" IGNORE!! but I can not find an example on the internet. The script I have made so far is below. <?php $sql = "SELECT * FROM sales WHERE category='$_POST[category]' AND manufacturer='$_POST[manufacturer]' AND model='$_POST[model]' AND purchasetype='$_POST[type]'"; // IF VALUE OF SAY MODEL IS LEFT BLANK - I WANT THE PHP TO INGORE THE TYPE OF MODEL AND SHOW THE RESULTS JUST INCLUDING THE OTHER FIELDS. $result = mysqli_query($cxn,$sql) or die ("Couldn't execute query"); $num = mysqli_num_rows($result); if ($num >0) // Login Name found { while($row = mysqli_fetch_assoc($result)) { ?> Similar TutorialsHow can I ignore - when doing claculations? e.g. 150 - 50 = 100 150 - 225 = -75 // I WANT to display only 75 and ignore the - sign i have a script that calls for a field, but if you arent on a blackberry it asks you to select a name first, so it gives error until you select: Notice: Undefined variable: posteid in E:\Website\citycore\2\mobile\schedule.php on line 20 i could make it so it didnt call for $posteid until after the name is selected, but then it wont work from the blackberry as it detects the pin number first. I have the following Query: Code: [Select] $query = "INSERT INTO characters SET psalt = '" .$salt. "'"; However, when the salt is generated, it may contain a ', thus stopping the Query. I need to know how I could make it so the Query would be unaffected by the ' in the salt value. Thanks! im trying to insert $myusername into a table only if $myusername does not exist is best to call the insert ignore or is there better way of doing this? also trying to make a list of logged in users which is allways updating when the page is auto refreshed whats the best to go about checking if the users is still there. EDIT: I solved it! ignore Below is some code I have that I would like to connect to databases that reside on different physical machines. The problem I can't seem to solve is how to ignore machines that are unreachable. Code: [Select] <html> <head> </head> <body> <?php $mysql_conn=new mysqli('192.168.1.67','admin','password','monkey'); $result=$mysql_conn->query("SELECT * from testtable"); echo "<table>"; echo "<th>Test Query</th>"; while ($row=$result->fetch_array(MYSQL_ASSOC)){ echo "<tr><td>"; echo $row['test1']; echo "</td></tr>"; } echo "</table>"; $mysql_conn=new mysqli('192.168.1.126','admin','','monkey1'); $result=$mysql_conn->query("SELECT * from demo"); echo "<table>"; echo "<th>Test Processor</th>"; while ($row=$result->fetch_array(MYSQL_ASSOC)){ echo "<tr><td>"; echo $row['name']; echo "</td></tr>"; } echo "</table>"; $mysql_conn=new mysqli('192.168.1.127','admin','','monkey2'); $result=$mysql_conn->query("SELECT * from demo"); echo "<table>"; echo "<th>Test Processor</th>"; while ($row=$result->fetch_array(MYSQL_ASSOC)){ echo "<tr><td>"; echo $row['processor']; echo "</td></tr>"; } echo "</table>"; ?> </body> </html> If 192.168.1.126 is offline, the webpage doesn't go any further and display 192.168.1.127's info...Appreciate any insight... Having a problem with that "insert ignore into". If it is a new record, it works, when it is a excisting record that needs to be updated, it is giving me this error: Cannot execute query: INSERT IGNORE INTO (gedcom,kennel) VALUES ("World","Avongara") What or where is it going wrong? This message is for me not enough to find the problem. $kennels = array(); if( !in_array( $kennel, $kennels ) ) array_push( $kennels, $kennel ); foreach( $kennels as $kennel ) { $query = "INSERT IGNORE INTO $kennels_table (gedcom,kennel) VALUES (\"$tree\",\"$kennel\")"; $result = @mysql_query( $query ) or die ("$admtext[cannotexecutequery]: $query"); } Thanks for helping I have a pspell script and I want it to ignore upper case. ie at the moment if I check spelling for say christopher it returns spelling error of Christopher (upper case C) <?php $query = 'helllo'; $pspell_config = pspell_config_create("en"); pspell_config_ignore($pspell_config, 5); pspell_config_mode($pspell_config, PSPELL_FAST); pspell_config_personal($pspell_config, "/home/*/public_html/custom.pws"); pspell_config_repl($pspell_config, "/home/*/public_html/custom.repl"); $pspell_link = pspell_new_config($pspell_config); $words = preg_split ("/\s+/", $query); $ii = count($words); global $spellchecked; $spellchecked = ""; for($i=0;$i<$ii;$i++){ if (pspell_check($pspell_link, $words[$i])) { $spellchecked .= $words[$i]." "; } else { $erroneous = "yes"; $suggestions = pspell_suggest($pspell_link, $words[$i]); $spellchecked .= $suggestions[0]." "; } } if($erroneous == "yes") { $spellchecked2 = str_replace(" ", "+", $spellchecked); echo "Did you mean: <a href=GetSearchResults.php?Query=$spellchecked2&catID=&siteID=3><i>".$spellchecked."</a></i>?"; } else { echo $spellchecked . " is a valid word/phrase"; } ?> Hi I'm currently experiencing a problem with my query. I've used the `INSERT IGNORE` option in my query and it works pretty well not to add duplicates, but the problem is that if my unique field match it doesn't update any other info in the row, is there maybe another option to update a row if an existing field exists but insert new row if it doesn't exists?
my current query is as follow
$query = mysqli_query($con,"INSERT IGNORE INTO mxit (ip,time,user_agent,contact,userid,id,login,nick,location,profile)
VALUES ('$ip','$post_time','$mxitua','$mxitcont','$mxituid','$mxitid','$mxitlogin','$mxitnick','$mxitloc','$mxitprof')") or die(mysqli_error($con));
I am working on a little project for my site and I am trying to get this script to ignore the index.html file and the .htaccess file in there. I just want it to display all files like .zip, .rar, .tar, .gz, .gtar, .ace, ect... echo " <td width='70%'><select id='download'>"; echo " <option value=''>None</option>"; if ($handle = opendir("./modules/Downloads/files")) { while (false !== ($file = readdir($handle))) { if ($file != "." && $file != "..") { echo " <option value='".$file."'>".$file."</option>"; } } closedir($handle); } echo " </td>\n"; This topic has been moved to MySQL Help. http://www.phpfreaks.com/forums/index.php?topic=309981.0 I want half of the results to to show up with a hyperlink (if I've added the link as a field in my CSV file) and half of the results to show up with no hyperlink. The link URL's are located in field 8 of a database : [8] as seen below. Could anyone help me to figure out how to add an "if" statement perhaps? Something like "if 8 true" then display "<a href"? I did not write this php code I am only modifying it. The csv file is very very straightforward, but this PHP is beyond me.

This topic has been moved to PHP Regex. http://www.phpfreaks.com/forums/index.php?topic=345658.0 Hello there, I am working on a script that will take a user submitted text and display the text in rainbow. I found a very nice function on the Internet and used it as my base. Here is an example of the code. Code: [Select] function rainbow($text) { /*** initialize the return string ***/ $ret = ''; /*** an array of colors ***/ $colors = array( 'ff00ff', 'ff00cc', 'ff0099', 'ff0066', 'ff0033', 'ff0000', 'ff3300', 'ff6600', 'ff9900', 'ffcc00', 'ffff00', 'ccff00', '99ff00', '66ff00', '33ff00', '00ff00', '00ff33', '00ff66', '00ff99', '00ffcc', '00ffff', '00ccff', '0099ff', '0066ff', '0033ff', '0000ff', '3300ff', '6600ff', '9900ff', 'cc00ff'); /*** a counter ***/ $i = 0; /*** get the length of the text ***/ $textlength = strlen($text); /*** loop over the text ***/ while($i<=$textlength) { /*** loop through the colors ***/ foreach($colors as $value) { if ($text[$i] != "") { $ret .= '<span style="color:#'.$value.';">'.$text[$i]."</span>"; } $i++; } } /*** return the highlighted string ***/ return $ret; } $post[message] = rainbow($post[message]); And it works very well Here is my problem. At times $post[message] will contain some basic html such as a bold tag, user smiley (img tag), a link tag, and so forth. How can I take my function above so that it doesn't edit and add the html font color coding for anything inside html tags where it just skips over them and leaves that part alone? I need this otherwise it will breakup every html tag I might have inside $post[message] and add a font color html tag to it, thus voiding all other html in it. hi, also i have an array with this values: $a=array('111-aa-zz-4','222-aa-zz-6','333-aa-zz-5'); and i want to sort(); this array, but it must ignore the numbers behind -aa-zz- also 4,6,5 how should i do this? best regards, tastro I apologize in advance, I know pretty much nothing about PHP - don't hate me, please! But I'm working on a form mailer, and it functions, but what I don't like is it leaves all the text fields, blank or not, in my email, which makes it difficult for my client to read, so theres a long list of txt field1: another text field: blah blah: all the way down the email - and I want it gone! haha. I've researched how to do this, but basically, I have no idea how to implement it into my code and don't have time right now to up and learn PHP. My code is as follows: Code: [Select] <?php //--------------------------Set these paramaters-------------------------- // Subject of email sent to you. $subject = 'PCI Tour/Excursion Request'; // Your email address. This is where the form information will be sent. $emailadd = 'MY EMAIL HERE'; // Where to redirect after form is processed. $url = 'FORWARDING URL'; // Makes all fields required. If set to '1' no field can not be empty. If set to '0' any or all fields can be empty. $req = '0'; // --------------------------Do not edit below this line-------------------------- $text = "Results from form:\n\n"; $space = ' '; $line = ' '; foreach ($_POST as $key => $value) { if ($req == '1') { if ($value == '') {echo "$key is empty";die;} } $j = strlen($key); if ($j >= 20) {echo "Name of form element $key cannot be longer than 20 characters";die;} $j = 20 - $j; for ($i = 1; $i <= $j; $i++) {$space .= ' ';} $value = str_replace('\n', "$line", $value); $conc = "{$key}:$space{$value}$line"; $text .= $conc; $space = ' '; } mail($emailadd, $subject, $text, 'From: '.$emailadd.''); echo '<META HTTP-EQUIV=Refresh CONTENT="0; URL='.$url.'">'; ?> IT was a very simple copy-paste form, but I have no idea what on earth I'm doing. If anyone has any ideas I would GREATLY appriciate the help! Thanks! -Austin Hello - I've come to an issue with something I'm working on and have searched around with no luck. When editing user accounts I want it to not be able to change the e-mail address into existing ones on other rows, but when submitting the form it takes into account that this particular rows email address is the same as the one which was sent via $_POST and throws up the error. The desired behaviour I want is for it to ignore the ID of the row which was posted, but take into account every other row. Here's the code as it stands at the moment: $email = $_POST['email']; $checkemail = mysql_query("SELECT email FROM users WHERE email='$email'"); } if (mysql_num_rows($checkemail) > 0) { return $this->error("The e-mail address you provided is already associated with an account."); } Hey Guys. I am working with a form that shows the grand total on the checkout page. The value of the grand total is inside a hidden field. When click on submit, the _POST array doesn't get back the last value of the grand total. I need to hit the button twice to get the last value. The weird thing is when I echo the value of the grand total it display the latest value, but not with the POST array
For example. If the grand total is $10.00 and I click on submit. It will show the POST['grand_total'] as empty. If I click on submit again it will show the grand total of $10.00.
Below is my code that I am working with. Any help would be really appreciated.
if(isset($_POST['submit'])) {
/* Doesn't show if i put it after if($_POST['submit'] */
if(isset($_POST['grand_total'])) {
echo $_POST['grand_total'];
}

$cart_totals = new cartTotals($subtotal, $discounted_amount,$post_values->tip); // Cart class is shown below
/* Doesn't show if i put it before if($_POST['submit'] */
if(isset($_POST['grand_total'])) {
echo $_POST['grand_total'];
}
echo "<input name='grand_total' type='hidden' value='$cart_totals->grand_total' />"; // Shows the grand total after second from submission
echo "$cart_totals->grand_total"; // Shows grand total after the first submission
