PHP - dynamic fields array not - php

Question

I have a form with dynamic fields. When I add a dynamic field and do a var_dump of that field, I am getting only the first result.
Form:
<div class="form-group halltype">
<label class="col-sm-2 col-sm-2 control-label">HallType</label>
<div class="col-sm-10">
<input type="text" class="form-control" name="title1[]" placeholder="Main Title"><br />
<input type="text" class="form-control" name="title2[]" placeholder="Title 2"><br />
<input type="text" class="form-control" name="seating[]" placeholder="Seating Capacity"><br />
<input type="text" class="form-control" name="floating[]" placeholder="Floating Capacity"><br />
</div>
</div>
<div class="form-group addhalltype">
<label class="col-sm-2 col-sm-2 control-label"></label>
<div class="col-sm-10">
<input type="button" class="btn btn-info" id="">Add Hall Type</button>
</div>
Jquery:
$(".addhalltype").click(function() {
$halltype = '<div class="form-group halltype"><label class="col-sm-2 col-sm-2 control-label">HallType</label><div class="col-sm-10"><input type="text" class="form-control" name="title1[]" placeholder="Main Title"><br /><input type="text" class="form-control" name="title2[]" placeholder="Title 2"><br /><input type="text" class="form-control" name="seating[]" placeholder="Seating Capacity"><br /><input type="text" class="form-control" name="floating[]" placeholder="Floating Capacity"><br /></div></div>';
$($halltype).insertBefore(".addhalltype");
});
and if I do var_dump($_POST['title1']), I get
array(1) {
[0]=>
string(4) "1212"
}

Answer 1

you are printing $_POST['title1'] in var_dump it will show you only value that u inserted for name="title1[]".
Here you are using dynamic array but with different name ie name equal to title1[] title1[] seating[] and floating[].
if you want to get all the post values in one name like title[0],title[1],...title[n] to get the result in this format you have to write your above code with this format.
<input type="text" class="form-control" name="title[]" placeholder="Main Title"><br />
<input type="text" class="form-control" name="title[]" placeholder="Title 2"><br />
<input type="text" class="form-control" name="title[]" placeholder="Seating Capacity"><br />
<input type="text" class="form-control" name="title[]" placeholder="Floating Capacity"><br />
