GET and POST work the same way, so you could use either.

Dear Ray
I was thinking like that but can't figure out to pick the value of the field from child page as in my parent page inside the div it shows like
<?php echo((isset($WA_section_1586802530391))?$WA_section_1586802530391->Body:"") ?>
but on the child page the actual value which i need to pick is <?php echo($bookSection->getColumnVal("SectionID")); ?>
Pls guide me here.
=============================
Here is the code of my parent page
<div class="row">
<form action="index.php" method="post" id="jumpbooks" title="For book change" accept-charset="UTF-8">
<div id="book" class="col-sm">
<select name="book" class="custom-select" id="book" onChange="framework_load_plugin_url('section.php',document.getElementById('jumpbooks'),'section','../../','');return document.MM_returnValue">
<?php
while(!$hadithBookList->atEnd()) { //dyn select
?>
<option value="<?php echo($hadithBookList->getColumnVal("BookID")); ?>"<?php if (!(strcmp($hadithBookList->getColumnVal("BookID"), ($mainHadith->getColumnVal("BookID"))))) {echo "selected=\"selected\"";} ?>><?php echo($hadithBookList->getColumnVal("BookNameBD")); ?></option>
<?php
$hadithBookList->moveNext();
} //dyn select
$hadithBookList->moveFirst();
?>
<input type="submit">
</select>
</div>
<div class="col-sm" id="section"><?php echo((isset($WA_section_1586802530391))?$WA_section_1586802530391->Body:"") ?>
</div>
</form>
</div>
----------------------------------------
I think in order to send query by GET method I have to use another form to pick the value and then pass to URL as in this present form if i select GET method the drop down does not work,
