My prof hasn't gotten back to me and he doesn't seem like even he knows how to do it so I'm posting here for some help. We've barely done any script writing yet and I can't seem to figure out how to go about doing it. He wants us to modify the existing script so that it generates a random number from 1 - 1000 and then counts the number of guesses and outputs how many guesses at the end. It won't open in the browser so I'm not sure what's wrong. Any help would be much appreciated! This is what I have so far: <?php if (!isset($_POST["guess"])) { $message = "Welcome to the guessing machine!"; $_POST["numtobeguessed"] = rand(1,1000); $_POST["counter"] = 0; } else if ($_POST["guess"] > $_POST["numtobeguessed"]) { $message = $_POST["guess"]." is too big! Try a smaller number."; $_POST["counter"]++; } else if ($_POST["guess"] < $_POST["numtobeguessed"]) { $message = $_POST["guess"]." is too small! Try a larger number."; $_POST["counter"]++; } else { // must be equivalent $message = "Well done! It took you '$_POST["counter"]' tries!"; } ?> <html> <head> <title>A PHP number guessing script</title> </head> <body> <h1><?php echo $message; ?></h1> <form action="" method="POST"> <p><strong>Type your guess here:</strong> <input type="text" name="guess"></p> <input type="hidden" name="numtobeguessed" value="<?php echo $_POST["numtobeguessed"]; ?>" ></p> <input type="hidden" name="counter" value="<?php echo $_POST["counter"]; ?>" <p><input type="submit" value="submit your guess"/></p> </form> </body> </html>

Hello, to start off I am very new to this and trying to learn as I go by using sample code and putting things together as I need them. I am working on a basic database editor that will make a select able list from a sql table. In this case, "Employees". Then, after I select a name from that list it gives me the option to alter that information and save it. What I am missing however, is the option to pre-fill what the database already has while in the edit part. The drop down menu only shows the Employee name. So when I select the name, only the EmpID variable is transferred to the next part. I want all fields pre-filled out by defining variables from the SQL table. So I cant figure out how to call the database, then the table, Find the PRIMARY KEY (which is the EmpID) and create variables from (FirstName, LastName and Pay), but only for the EmpID that was slected before hand. How can I do this? Once I can make those variables, I can use them to pre-fill the text areas.. Thank you in advance. Also if needed I will post the code I have so far. <html> <head> <title>Edit Employee</title> </head> <body> <?php $dbhost = 'localhost'; $dbuser = 'Labor'; $dbpass = '***********'; $conn = mysql_connect($dbhost, $dbuser, $dbpass); // Check connection if(! $conn ) { die('Could not connect: ' . mysql_error()); } if(isset($_POST['save'])) { $EmpID = $_POST['EmpID']; $FirstName = $_POST['FirstName']; $LastName = $_POST['LastName']; $Pay = $_POST['Pay']; $OrgEmpID = $_POST['OrgEmpID']; $sql = "UPDATE Employees SET EmpID='$EmpID', FirstName='$FirstName', LastName='$LastName', Pay='$Pay' WHERE EmpID='$OrgEmpID'"; mysql_select_db('Labor'); $retval = mysql_query( $sql, $conn ); if(! $retval ) { die('Could not update data: ' . mysql_error()); } echo "Updated data successfully\n"; } else { if(isset($_POST['select'])) { $EmpID = $_POST['EmpID']; $FirstName = $_POST['FirstName']; $LastName = $_POST['LastName']; $Pay = $_POST['Pay']; $OrgEmpID = $_POST['EmpID']; echo ' Update Employee <form method="post" action="'.$_PHP_SELF.'"> <table width="400" border="0" cellspacing="1" cellpadding="2"> <tr> <td width="100">Employee ID: </td> <td><input name="EmpID" type="text" id="EmpID" value="'.$EmpID.'"></td> </tr> <tr> <td width="100">First Name: </td> <td><input name="FirstName" type="text" id="FirstName" value="'.$FirstName.'"></td> </tr> <tr> <td width="100">Last Name: </td> <td><input name="LastName" type="text" id="LastName" value="'.$LastName.'"></td> </tr> <tr> <td width="100">Hourly Pay: </td> <td><input name="Pay" type="text" id="Pay" value="'.$Pay.'"></td> </tr> <tr> <td width="100"> </td> <td> </td> </tr> <tr> <td width="100"> </td> <td> <input type="hidden" name="OrgEmpID" value="'.$OrgEmpID.'"> <input name="save" type="submit" id="save" value="Save"> </td> </tr> </table> </form> '; } else { ?> <form method="post" action="<?php $_PHP_SELF ?>"> <table width="400" border="0" cellspacing="1" cellpadding="2"> <tr> <td width="100">Select Employee to Edit</td> <td></td> </tr> <tr> <td width="100"> <select name="EmpID" id="EmpID"> <option value='EmpID' disabled='disabled' selected='selected'>Please select a name</option> <? mysql_select_db('Labor'); $result = mysql_query('SELECT EmpID, FirstName, LastName, Pay FROM Employees'); while ($row = mysql_fetch_array($result)) { echo '<option value="'.$row{"EmpID"}.'">'.$row{"FirstName"}.'

Good afternoon, I am able to retrieve results from yahoo with my API key, using the instructions found here: http://developer.yahoo.com/boss/search/boss_api_guide/codeexamples.html# Code: <?php require("OAuth.php"); $cc_key = "your consumer key here"; $cc_secret = "your consumer secret here"; $url = "<http://yboss.yahooapis.com/ysearch/news>,web,images"; $args = array(); $args["q"] = "yahoo"; $args["format"] = "json"; $consumer = new OAuthConsumer($cc_key, $cc_secret); $request = OAuthRequest::from_consumer_and_token($consumer, NULL,"GET", $url, $args); $request->sign_request(new OAuthSignatureMethod_HMAC_SHA1(), $consumer, NULL); $url = sprintf("%s?%s", $url, OAuthUtil::build_http_query($args)); $ch = curl_init(); $headers = array($request->to_header()); curl_setopt($ch, CURLOPT_HTTPHEADER, $headers); curl_setopt($ch, CURLOPT_URL, $url); curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE); $rsp = curl_exec($ch); $results = json_decode($rsp); print_r($results); ?> However the output of results is very bizarre, for example, if I search for elephant, I get the following results (partial copy and paste): stdClass Object ( [bossresponse] => stdClass Object ( [responsecode] => 200 [images] => stdClass Object ( [start] => 0 [count] => 35 [totalresults] => 108000 [results] => Array ( [0] => stdClass Object ( [clickurl] => http://0.tqn.com/d/goafrica/1/0/Y/Q/IMG_1592.JPG [size] => 2.2MB [format] => jpeg [height] => 2432 [refererclickurl] => http://goafrica.about.com/od/africanwildlife/ss/The-Big-5-Images-Facts-And-Information-About-Africas-Big-Five_2.htm [refererurl] => http://goafrica.about.com/od/africanwildlife/ss/The-Big-5-Images-Facts-And-Information-About-Africas-Big-Five_2.htm [title] => African Elephant - One of the "Big Five" - African Elephant Image ...

I am completing a fast track learning course where we don`t have time to learn the basics, we are in the deep end! Does anyone have suggestions on how to display the results properly? Thanks! Note: I had tried to do it this way (which worked with the Google API - although the links were not clickable).. It did not work at all with Yahoo: foreach ($results->{ 'items' } as $item ) { echo $item->{ 'title' }.": ".$item->{ 'link' }."\n\n"; echo $newline; }
