    <p>I am new to scripting and web development. I am displaying a CSV file in the pagination format. The code to display the CSV file is as below. </p> <pre><code>&lt;?php $names = file('demo.csv'); $page = $_GET['page']; //constructor takes three parameters //1. array to be paged //2. number of results per page (optional parameter. Default is 10) //3. the current page (optional parameter. Default is 1) $pagedResults = new Paginated($names, 20, $page); $handle = fopen('demo.csv', 'r'); if (($data = fgetcsv($handle, 1000, ',')) !== FALSE) { } echo "&lt;table border='3' bgcolor='#dceba9' style='float:center; margin:50'&gt;"; echo '&lt;tr&gt;&lt;th&gt;'.implode('&lt;/th&gt;&lt;th&gt;', $data).'&lt;/th&gt;&lt;/tr&gt;'; //when $row is false loop terminates while ( $row = $pagedResults-&gt;fetchPagedRow()) { echo "&lt;tr&gt;&lt;td&gt;"; //echo '&lt;tr&gt;&lt;th&gt;'.implode('&lt;/th&gt;&lt;th&gt;', $data).'&lt;/th&gt;&lt;/tr&gt;'; $row1 = str_replace( ',', "&lt;/td&gt;&lt;td&gt;", $row ); echo $row1; echo "&lt;/td&gt;&lt;/tr&gt;"; } fclose($handle); echo "&lt;/table&gt;"; //important to set the strategy to be used before a call to fetchPagedNavigation $pagedResults-&gt;setLayout(new DoubleBarLayout()); echo $pagedResults-&gt;fetchPagedNavigation(); //$data1 = []; $total_columns = 0; $handle1 = fopen('demo.csv', 'r'); while (false !== ($row = fgetcsv($handle1, 1000, ','))) { 0 === $total_columns and $total_columns = count($row); $i = 1; while (++$i &lt;= $total_columns) { $data1[$i][] = (int) $row[$i - 1]; } } $i = 0; while (++$i &lt;= $total_columns) { $_SESSION["min-column-$i"] = min($data1[$i]); $_SESSION["max-column-$i"] = max($data1[$i]); } $_SESSION['totalcolumns'] = $total_columns; fclose($handle1); ?&gt; </code></pre> <p>Now, based on the number of columns of the CSV file I need those many sliders. For the sliders the minimum and maximum values are based on the minimum and maximum values of the columns. The code for that is as below. </p> <pre><code>&lt;?php include 'index.php'; ?&gt; &lt;?php $totalcolumns = $_SESSION["totalcolumns"]; ?&gt; &lt;!-- Activate Simple Slider on your input --&gt; &lt;h2&gt;Keyword Scores&lt;/h2&gt; &lt;?php $i = 1; while (++$i &lt;= $_SESSION['totalcolumns']) { $range = $_SESSION["min-column-$i"] . ',' . $_SESSION["max-column-$i"];?&gt; &lt;br&gt;&lt;?php echo "Keyword" ?&gt; &lt;?php echo $i -1 ?&gt; &lt;br&gt;&lt;input type="text" data-slider="true" data-slider-range="&lt;?php echo $range ?&gt;" data-slider-step="1"&gt; &lt;?php } ?&gt; &lt;form action = "update.php" method="post"&gt;&lt;input type="submit" name="submit"value="SUBMIT"&gt;&lt;/form&gt; &lt;script&gt; $("[data-slider]") .each(function () { var range; var input = $(this); $("&lt;span&gt;").addClass("output") .insertAfter(input); range = input.data("slider-range").split(","); $("&lt;span&gt;").addClass("range") .html(range[0]) .insertBefore(input); $("&lt;span&gt;").addClass("range") .html(range[1]) .insertAfter(input); }) .bind("slider:ready slider:changed", function (event, data) { $(this).nextAll(".output:first") .html(data.value.toFixed(2)); }); &lt;/script&gt; </code></pre> <p>Now, when I select the values in the slider and click on "<strong>SUBMIT</strong>" button, I should get the display of CSV updated accordingly. (i.e) only the rows satisfying the sliders should be displayed. I am not sure of how to do this part as I tried to include one more PHP file. But am not able to pass the values to the PHP file. Can someone please help me on this part?</p>

    2. COI am not aware of it. Is it possible to send the entire array of values using ajax? For example, if I have 5 sliders, can I send all the 5 values using ajax?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
