PHP - Verify A Value In An Array
I need to verify a submitted value with one I have in an array.
Example... <input type="hidden" name="page" id="fb_page" value="<?php echo htmlentities(substr($_SERVER['SCRIPT_NAME'], 1)); ?>" /> $pages = array( '1' => 'One', '2' => 'Two', '3' => 'Three', '4' => 'Four' ); I need to say if the value == 'One' then echo 1. Keep mind that the array is in an external file. The post is in the footer and the echoed data is in another file. Essentially I am posting '1' to the database and then I want 'One' echoed out if it matches the value in the array. Similar TutorialsHi, I have created some code that picks a winning lottery ticket number based on the New York "Take 5" lottery. It uses the winning number (as an offically generated random number that i cannot cheat with) as a seed for the rand() function. This way it will always give the same result for that particular seed making it 100% transparent and that i cannot manipulate the results (without changing the code which will be published). The code is: Code: [Select] <?php if (isset($_POST['submit'])){ $seed = $_POST['take5numbers']; $ticketssold = $_POST['tickets']; srand ($seed*13579); $random_number = rand(1,$ticketssold); echo "Winning ticket is $random_number"; }else{ ?> <form name="form1" method="post" action="result.php"> "Take 5" numbers from low to high (including leading 0's) <input type="text" name="take5numbers" id="end" size="20" /><br> Total tickets sold for round <input type="text" name="tickets" id="end" size="20" /><br> <input type="submit" name="submit" id="submit" value="Get Winning Ticket Number!"> </form> <? } ?> Can someone please tell me if the code is generating fair and unbias results? Hi all, I'm trying to add a section where it verifies that the email address is active in my register code. My code below is it checking the dnsrr, and if it is not real, I have it die and an error message appears. However, I am getting the error message all the time, whether I am sure the email is working or not. First I declared my email variable ($email), and then after the code below I of course insert the new data in to the database. I'm doing this over my localhost, so is that why it can't verify emails? Or am I setting this up wrong? Code: [Select] <?php $email = trim($_POST['email']); if (False !== strpos($email, '@')) die("Please type in an email address.<br><br><a href=register.php>Continue</a>"); if(!@checkdnsrr($mailDomain,'MX')) die("Not real email address. Please try again.<br><br> <a href=register.php>Continue</a>"); ?> I am making a secure registration for my website and looking for a function that will verify with a user inputted date exists. From my registration html form I am putting a month, day and year , each inputted separately into a single variable: Code: [Select] $bday = $year . "-" . $month . "-" . $day; My birthday input looks like: Code: [Select] <div class=\"Container FormBoxLeft\"> <b>Birthdate:</b> </div> <div class=\"Container FormBoxRight\"> <select name=\"month\"><option value=\"\">-Month-</option> <option value=\"01\">January</option> <option value=\"02\">February</option> <option value=\"03\">March</option> <option value=\"04\">April</option> <option value=\"05\">May</option> <option value=\"06\">June</option> <option value=\"07\">July</option> <option value=\"08\">August</option> <option value=\"09\">September</option> <option value=\"10\">October</option> <option value=\"11\">November</option> <option value=\"12\">December</option> </select> <select name=\"day\"> <option value=\"\"> -Day-</option>'; //Print 31 Days "; for ($x=1; $x<=31; $x++) { echo "<option value='".$x."'"; if(isset($_POST['submit']) && $day == $x) { echo " selected"; } echo ">".$x."</option>\n"; } echo "</select> <input name=\"year\" size=\"2\" maxlength=\"4\" type=\"text\"> So.. What I am asking is.. is there a secure way to check if the date the user inputted exists, or is there a better way to make the form more secure from that part. Upon finding the users birthdate I am also wanting to check if the user is a certain age. Hello, I made an login script, it works but i want to be sure if its secure to use in everyday use, here is the script: <?php session_start(); require_once('include/config.inc.php'); require_once('include/functions.php'); function clean($str, $encode_ent = false) { $str = @trim($str); if ($encode_ent) { $str = htmlentities($str); } if (version_compare(phpversion(),'4.3.0') >= 0) { if (get_magic_quotes_gpc()) { $str = stripslashes($str); } if (@mysql_ping()) { $str = mysql_real_escape_string($str); } else { $str = addslashes($str); } } else { if (!get_magic_quotes_gpc()) { $str = addslashes($str); } } return $str; } if (isset($_POST['submit'])) { if ($_POST['code'] == $_SESSION['rand_code']) { //Sanitize the POST values $username = clean($_POST['username']); $password = clean($_POST['password']); $ip = clean($_SERVER['REMOTE_ADDR']); $query="SELECT * FROM user WHERE username='$username' AND password='".md5($_POST['password'])."'"; $result=mysql_query($query); //Check whether the query was successful or not if ($result) { if (mysql_num_rows($result) == 1) { //Login Successful session_regenerate_id(); $user = mysql_fetch_assoc($result); $_SESSION['SESS_MEMBER_ID'] = $user['username']; session_write_close(); $query_login_ok = "INSERT INTO logs (`username`, `password`, `result`, `ip`) VALUES ('$username', '$password', 'SUCCESS', '$ip');"; $result_query_login_ok = mysql_query($query_login_ok) or die('MYSQL ERROR'); header("location: pmt.php"); exit(); } else { //Login failed $query_login_fail = "INSERT INTO logs (`username`, `password`, `result`, `ip`) VALUES ('$username', '$password', 'FAILED', '$ip');"; $result_query_login_fail = mysql_query($query_login_fail) or die('MYSQL ERROR'); header("location: index.php"); exit(); } } else { die("ERROR"); } } } ?> <form id="login" name="login" method="post" action=""> <table width="300" border="0" align="center" cellpadding="2" cellspacing="0"> <tr> <td width="112"><b>Username</b></td> <td width="188"><input name="username" type="text" class="textfield" id="username" value="admin" /></td> </tr> <tr> <td><b>Password</b></td> <td><input name="password" type="password" class="textfield" id="password" value="qazwsx" /></td> </tr> <img src="include/captcha.php"/> <tr> <td><b>Code</b></td> <td><input type="text" name="code" /></td> </tr> <tr> <td> </td> <td><input type="submit" name="submit" value="Login" /></td> </tr> </table> </form> Hi, suppose I want to write a PHP script that checks whether a valid email address exists or not. There are a number of GUI-based tools to verify this, but is there any command line tool to do the same so that I can use PHP to capture the output? function isValidEmail($email){ return eregi("^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,3})$", $email); } How do I incorporate the code above into my code?? Code: [Select] <?php error_reporting(E_ALL ^ E_NOTICE); ?> <?php // make sure the form has actually been submitted . . . if( strtolower($_SERVER['REQUEST_METHOD']) === 'post' ) { // 1. Create a database connection $connection = mysql_connect("localhost", "root", "maven777"); if(!$connection){ die("Database connection failed: " .mysql_error()); } // 2. Select a database to use $db_select = mysql_select_db("homesloans", $connection); if(!$db_select){ die("Database selection failed: " .mysql_error()); } $radius = ($_POST['radius']); $type = ($_POST['type']); $price = ($_POST['price']); $bedrooms = ($_POST['bedrooms']); $bathrooms = ($_POST['bathrooms']); $parking = ($_POST['parking']); $city = ($_POST['city']); $details = ($_POST['details']); $firstname = ($_POST['firstname']); $lastname = ($_POST['lastname']); $email = ($_POST['email']); $phone = ($_POST['phone']); $query="INSERT INTO leads (leadid, city, radius, type, price, bedrooms, bathrooms, parking, details, firstname, lastname, email, phone) VALUES('NULL', '[$city]', '[$radius]', '[$type]', '[$price]', '[$bedrooms]', '[$bathrooms]', '[$parking]', '[$details]', '[$firstname]', '[$lastname]', '[$email]', '[$phone]')"; mysql_query($query) or die ('Error updating database'); echo "Database Successfully Updated."; // not necessarily.

(Tried all of the above with Nested Loops also) Edited May 1, 2020 by AlphaMikeTags hi i am trying to make a payroll calculator script that takes employee info, calculates pay, displays submitted info in a table, stores info in an array, and updates the array when new info is submitted. i have most of these accomplished, i am having trouble with the "store into an array, and update the array when new info is submitted" parts of the project. i am still not very fluent in php so there may be easier ways to achieve what i have so far. any pointers would be a great help, this part has got me stumped. I am having some problems getting a query correct. Basically I have two tables, one with listings and another with categories. In the listings table I have a column called shortdescription. I am trying to pull the shortdescription from the listings table with the query $shortdesc = array_shift(mysql_fetch_row(mysql_query("select shortdescription from links where category = '".$scat->id."' "))); The shortdecription display properly on the pages display the listings, however I am getting the following error on any pages that only display the parent categories Warning: array_shift() [function.array-shift]: The argument should be an array in /home/...path/file.php on line 1462 The listings id numbers begin at 75+ because the initial parent category id ends at 74. The query seems to be searching for listing ids below 75 and spitting out an error because it is not finding them. Any ideas on how to eliminate this error and/or stop the query from looking for non-existant data? How can i save array from inputs, witch is $igraci and it have 5 values, to mysql base, i tryed but in mysql it shows Array. This is form: <form action="dodaj_klan.php" method="post" > <p> <label>Naziv klana:</label> <input name="naziv" type="text" size="20%" /> <label>Web Sajt:</label> <input name="website" type="text" size="20%" /> <label>E-Mail:</label> <input name="email" type="text" size="20%" /> <br /><br /> <label>Igraci klana(5):</label> <input name="lider" type="radio" value="1" /> <input name="igraci[]" type="text" size="20%" /><br /> <input name="lider" type="radio" value="2" /> <input name="igraci[]" type="text" size="20%" /><br /> <input name="lider" type="radio" value="3" /> <input name="igraci[]" type="text" size="20%" /><br /> <input name="lider" type="radio" value="4" /> <input name="igraci[]" type="text" size="20%" /><br /> <input name="lider" type="radio" value="5" /> <input name="igraci[]" type="text" size="20%" /> <label><i>(obelezi lidera klana)</i></label> <br /><br /> <input class="button" type="submit" name="submit" value="Dodaj" /> </p> </form> Now i wonna save this igraci[] array in mysql, i tried like this but it doesn't work: $igraci = $_POST['igraci']; $query = "INSERT INTO klanovi (naziv, website, email, igraci) VALUES ('{$naziv}', '{$website}', '{$email}', '{$igraci}')"; $result = mysql_query($query, $connection); How can i do this? Thanks.. Using curl_multi, I have loaded up 3 url's and then printed the array. 1) How can I also set a timestamp on output to let me know when each url was run? 2) How can I explode the array to only display the data and timestamp, excluding the text "Array ( =>", "[1] =>", "[2] =>" and " )"? Code <?php function multiRequest($data, $options = array()) { // array of curl handles $curly = array(); // data to be returned $result = array(); // multi handle $mh = curl_multi_init(); // loop through $data and create curl handles // then add them to the multi-handle foreach ($data as $id => $d) { $curly[$id] = curl_init(); $url = (is_array($d) && !empty($d['url'])) ? $d['url'] : $d; curl_setopt($curly[$id], CURLOPT_URL, $url); curl_setopt($curly[$id], CURLOPT_HEADER, 0); curl_setopt($curly[$id], CURLOPT_RETURNTRANSFER, 1); // post? if (is_array($d)) { if (!empty($d['post'])) { curl_setopt($curly[$id], CURLOPT_POST, 1); curl_setopt($curly[$id], CURLOPT_POSTFIELDS, $d['post']); } } // extra options? if (!empty($options)) { curl_setopt_array($curly[$id], $options); } curl_multi_add_handle($mh, $curly[$id]); } // execute the handles $running = null; do { curl_multi_exec($mh, $running); } while($running > 0); // get content and remove handles foreach($curly as $id => $c) { $result[$id] = curl_multi_getcontent($c); curl_multi_remove_handle($mh, $c); } // all done curl_multi_close($mh); return $result; } $data = array(array(),array()); $data[0]['url'] = 'http://search.yahooapis.com/VideoSearchService/V1/videoSearch?appid=YahooDemo&query=Pearl+Jam&output=json'; $data[1]['url'] = 'http://search.yahooapis.com/VideoSearchService/V1/videoSearch?appid=YahooDemo&query=Black+Eyed+Peas&output=json'; $data[2]['url'] = 'http://search.yahooapis.com/VideoSearchService/V1/videoSearch?appid=YahooDemo&query=Nirvana&output=json'; $r = multiRequest($data); print_r($r); ?> Output Array ( => Pearl Jam [1] => Black Eyed Peas [2] => Nirvana ) Preferred Output 01:00:01 Pearl Jam 01:00:02 Black Eyed Peas 01:00:03 Nirvana Hello all, I have yet again trouble finding a logical solution to my problem. I'm fetching an array which can hold 1 or more values. The problem is, I want these values to ouput in my json_encode function, but this also needs to happen dynamically depending on the amount of values. I can't explain it further, so here's the code so far: Code: (php) [Select] $files = mysql_fetch_array($get_files); $a = count($files); $i = 1; while ($files) { $variablename = 'fileName' . $i; $$variablename = $files['fileName']; $i++; } $output = array( OTHER VALUES , 'fileName1' => $fileName1, 'fileName2' => $fileName2, 'fileName3' => $fileName3, ............); // How do I add the fileNames dynamically depending on how many there are? This got me thinking, I also need to dynamically GET the values with jQuery. How would I do that, when the above eventually works? Thank you. Hi there, Basic question, but I can't seem to find a page in the PHP docs that answers (though I'm sure such a one exists, I just can't seem to think up the right search terms - anyway) My question is: is there a short-hand way to use a value from an associative array as the key in another associative array? So for example, given this array: $the_array = array(0 => array('name': 'the_name', 'value' : 'the_value'), 1 => etc....); then this kind of foreach loop doesn't work Code: [Select] $new_data = array(); foreach($the_array as $element){ $new_data[$element['name']] = $element['value']; } Obviously I can just save out the values, like $name = $element['name'] --- but I was just wondering if there was a more efficient way to do it? Cheers, PS. I tried encapsulating with {} - i.e. $new_data[{$element['name']}] --- but that also fails. I need a help in the following : I have an admin page from where the admin attaches an gif image.This attached image should be shown to the user as a scrolling image. The code for the scrolling image is done through javascript. So my actual problem is getting the name of the attached gif image to the javascript array which is used for scrolling horizontally. This topic has been moved to PHP Applications. http://www.phpfreaks.com/forums/index.php?topic=344127.0 So I'm trying to create an Array from a comma separated string containing array{s}. How can I take a string full of comma separated hex values such as : <?php $myStr = ( "00ffff", "00cccc", "009999", "007777", "004444", "001111", "01ffff", "01cccc", "019999" ); ?> & turn it into 3 separated arrays like : <?php $myNewArrs = [ Array1 ( 3 ), Array2 ( 3 ), Array3 ( 3 ), ]; ?> which REALLY looks like :
<?php
$myNewArrs = [
Array ( "00ffff", "00cccc", "009999" ),
Array ( "007777", "004444", "001111" ),
Array ( "01ffff", "01cccc", "019999" ),
];
?>

Edited May 27 by AquariaXI I have mysql select query shown below retrieving data from a database:
$sql = "
SELECT
student, sum( test_score ) as score
FROM
test
INNER JOIN
level
ON
test.level_id = level.level_id
GROUP BY
student"
$result = $mysqli->query($sql, MYSQLI_STORE_RESULT);
if($result)
{
while ($row = $result->fetch_array(MYSQLI_ASSOC))
{
var_dump($row);
}
}
On inspection of the retrieved array with var_dump(), i have these result below:
array (size=2) 'John' => string 'English' (length=2) 'Score' => string '20' (length=3) array (size=2) 'Mary' => string 'Math' (length=3) 'Score' => string '35' (length=3) array (size=2) 'Samuel' => string 'Physics' (length=3) 'Score' => string '5' (length=3)How do I get at and print out the highest score from this set of array values within this context. I tried this echo max($row['count']) but i understandably got this feedback: Warning: max(): When only one parameter is given, it must be an array Thanks. Hi, I'm trying to explode an array into a multidimensional array using <br /> tags as splitters but just can't get the syntax right! I can do lines of the array one by one, but not the whole lot at once. I'd really appreciate a quick example of an explode inside an array. $myarray looks something like this with print_r: ( [0] => [1] => some_html<br />some_html<br />some_html<br /> [2] => some_html<br />some_html<br />some_html<br /> [3] => some_html<br />some_html<br />some_html<br /> ) and I want to turn it into this: ( [0] => [1] => [0]some_html [1]some_html [2]some_html [2] => [0]some_html [1]some_html [2]some_html [3] => [0]some_html [1]some_html [2]some_html ) I've tried this $myarray = explode ("<br />", $myarray); but it doesn't work … It doesn't matter too much if there's are a few empty lines in the array from the final <br /> tags. Many thanks, as ever, for any help. I have a associative array and I need to compare it to a normal array. Code: [Select] associative will have anywhere from 2-8 of these ['name'] ['color'] ['uid'] Code: [Select] normal array will have anywhere from 1-8 names ['name'] What I need to do is get the name of the people that are in the associative array that are not in the normal array. I've tried all sorts of different loops and what not and I cant seam to get anything to work in every case. |
