Foreach is showing only one result instead of all - php

Question

I'm trying to select elements from only one category and show them on page.
Currently I have 5 posts in this category but on page I see only one.
Why is that?
Here is how I try
<?php
$args = array(
'showposts'=>-1,
'category_name' => 'custom-page',
);
$query = new WP_Query( $args );
$aSolutionsePost = array();
if ( $query->have_posts() ) {
while ( $query->have_posts() ) {
$aSolutionsePost = array();
$query->the_post();
$aSolutionsePost['title'] = $query->post->post_title;
$aSolutionsePost['content'] = $query->post->post_content;
}
}
?>
<div class="col-4 ">
<ul class="price">
<?php if(!empty($aSolutionsePost)){?>
<?php foreach($aSolutionsePost as $item){ ?>
<li class="header"><?php echo $item->title; ?></li>
<li class="grey"><?php echo apply_filters('the_content',$item->content);?></li>
<?php }?>
<?php }?>
</ul>
</div>
When I print_r($aSolutionsePost); I see only one result. This:
Array (
[title] => Price test title
[content] => Price test content
[0] => Array (
[title] => Price test title
[content] => Price test content
)
)

Answer 1

This line of code inside your while ( $query->have_posts() ) loop:
$aSolutionsePost = array();
is overwriting the value of $aSolutionsePost each pass through the loop. You probably want something like this instead:
while ( $query->have_posts() ) {
$query->the_post();
$aSolutionsePost[] = array('title' => $query->post->post_title,
'content' => $query->post->post_content);
}
Note that in your code to echo the results, you are treating the array elements as objects, not associative arrays. It's simplest to just change those lines to this:
<li class="header"><?php echo $item['title']; ?></li>
<li class="grey"><?php echo apply_filters('the_content',$item['content']);?></li>
but if you want to keep that code the same you can change the assignment line to this:
$aSolutionsePost[] = (object)array('title' => $query->post->post_title,
'content' => $query->post->post_content);

Answer 2

Check array set inside while,
You re-create $aSolutionsePost every time, so it will be reseted.
Solution is to create new array and append it to $aSolutionsePost, check below snippet.
while ( $query->have_posts() ) {
$tmpSolutionsePost = array();
$query->the_post();
$tmpSolutionsePost['title'] = $query->post->post_title;
$tmpSolutionsePost['content'] = $query->post->post_content;
$aSolutionsePost[] = $tmpSolutionsePost;
}

Answer 3

You are actually updating the same array with new values in the loop.
$finalData =array();
while ( $query->have_posts() ) {
$aSolutionsePost = array();
$query->the_post();
$aSolutionsePost['title'] = $query->post->post_title;
$aSolutionsePost['content'] = $query->post->post_content;
$finalData[] = $aSolutionsePost;
}
Now iterate over $finalData.

Answer 4

This is because you are adding the element to same key of array again and again and that is why there is only 1 element in the array, hence foreach is showing only 1 element.
You should possibly take 2d array to solve this purpose.
