FAQ Content Management System using barcode printing for tomcat control to generate, create denso qr bar code image in tomcat applications. Microsoft Official Website same as the subjec QR for Java t_id field in the topics table (ON subjects.id = topics. subject_id), and then join this to the questions table (LEFT JOIN questions), in which the topic id is equal to the topic_id field in the questions table (ON topics.

id = questions.topic_id) where the whole query has the subject id of $validsub (WHERE subjects.id = $validsub) and the question is active (AND active = 1).

Display the results of the query in a table:. $toprow = mysql_fe tch_assoc($topresult); echo "<table class="visible" cellspacing=0 cellpadding=5>"; echo "<tr><th class="visible" colspan=2>Statistics</th></tr>"; echo "<tr>"; echo "<td>Total Topics</td><td>" . $toprow["numtopics"] . "</td>"; echo "</tr>"; echo "<tr>"; echo "<td>Total Questions</td><td>" .

$toprow["numquestions"] . "</td>"; echo "</tr>"; echo "</table>"; }. This section should look like Figure 9-2 when it s finished. FIGURE 9-2. The sidebar displays the relevant topics for the subject. Practical PHP and MySQL If no subject GET qrcode for Java variable exists, display the latest 10 questions:. echo "</table&g t;"; } else { $latqsql = "SELECT questions.id, question, subject FROM subjects, questions, topics WHERE questions.topic_id = topics.

id AND topics.subject_id = subjects.id AND active = 1 ORDER BY questions.

dateadded DESC;"; $latqresult = mysql_query($latqsql); $latqnumrows = mysql_num_rows($latqresult); echo "<h1>Latest Questions</h1>"; if($latqnumrows == 0) { echo "No questions!"; } else { echo "<ul>"; while($latqrow = mysql_fetch_assoc($latqresult)) { echo "<li><a href="answer.php id=" . $latqrow["id"] .

"">" . $latqrow["question"] . "</a> (<i>" .

$latqrow["subject"] . "</i>)</li>"; } echo "</ul>"; } }. Each question links to answer.php and passes the id of the question to it. NOTE Remember When per qr barcode for Java forming queries, remember to only return records only where the active field is set to 1. If this field is set to 0, the question is awaiting moderation. You will learn more about the question moderation system later in the project.

. Finally, add the footer file:. echo "</ul>"; } } require("footer.php"); > FAQ Content Management System This functionality swing QR Code should look similar to the page shown in Figure 9-3.. FIGURE 9-3. The interface provides a simple way to begin using the application. DISPLAYING QUESTIONS Questions and answ tomcat QR Code ISO/IEC18004 ers are the lifeblood of a FAQ site, and in this section, you create the code to display them. The functionality is spread across two pages. The first page (questions.

php) displays a summary of the questions inside the topic, and the second page (answer.php) displays the answer and comments for that specific question..

Displaying Question Summary Create a file call servlet QR Code 2d barcode ed questions.php and start adding the code:. < php session_s tart(); require("functions.php"); if(pf_check_number($_GET["topic"]) == TRUE) { $validtopic = $_GET["topic"]; } else { header("Location: " . $config_basedir); }.

Practical PHP and MySQL if(pf_check_number ($_GET["subject"]) == TRUE) { $validsubject = $_GET["subject"]; } else { header("Location: " . $config_basedir); }. In this block, you qr barcode for Java first validate the topic and submit GET variables. If the validation fails, the page redirects to the site s base page. Each question on this page includes a short summary of the answer, as shown in Figure 9-4.

. FIGURE 9-4 the question. The question summary provides a nice way to show the first line of To create this sho rt summary, you create a small function called question_summary():. header("Location: Quick Response Code for Java " . $config_basedir); } function question_summary($question) { $final = ""; $final = (substr($question, 0, 80) . ".

.."); return $final; }.

The question_summa ry() function is similar to the short_event() function that was created in the calendar project in the preceding chapter. The function uses substr() to cut out the first 80 letters, and then appends . Perform the query:.

return $final; } r qr codes for Java equire("header.php"); echo "<h1>Questions</h1>"; $qsql = "SELECT * FROM questions WHERE topic_id = " . $validtopic .

" AND active = 1;"; $qresult = mysql_query($qsql); $numrows = mysql_num_rows($qresult);. FAQ Content Management System If no records were returned, display No $numrows = mysql_n um_rows($qresult); if($numrows == 0) { echo "No Questions"; }. Questions:. Display the questi ons in the table:. echo "No Questions qr bidimensional barcode for Java "; } else { echo "<table cellspacing=0 cellpadding=5>"; while($qrow = mysql_fetch_assoc($qresult)) { echo "<tr>"; echo "<td><a href="answer.php id=" . $qrow["id"] .

"">" . $qrow["question"] . "</a></td>"; echo "<td><i>" .

question_summary($qrow["answer"]) . "</i></td>"; if($_SESSION["SESS_ADMINUSER"] AND $numrows >= 1) { echo "<td><a href="deletequestion.php topic=" .

$validtopic . "&subject=" . $validsubject .

"&questionid=" . $qrow["id"] . "">Delete Question</a></td>"; } echo "</tr>"; } echo "</table>"; }.

A while loop itera tes through each question returned and then displays the question and summary. If the administrator is logged in, a Delete Question link is added also. Finally, if the user is logged in, add a link to add a new question:.

echo "</table&g qr barcode for Java t;"; } if($_SESSION["SESS_USERNAME"]) { echo "<h2>Options</h2>"; echo "<a href="addquestion.php subject=$subject&topic=$topic"> Add a question</a>"; } require("footer.php"); >.
