I need some help with either my SQL or my PHP I do not know which...

Question

Hello I am creating a CMS and some of the functionality of it that the images that are within the content are managable. I currently trying to display a table that shows the the content title and then the associated images, ideally I would like a layout similar to this,

Content Title
Image 1
Image 2
Image 3
Content Title 2
Image 1
Image 2
Content Title 3
Image 1

The SQL the returns the data is actually formed using Codeigniters Active Record class,

function getAllContentImages() {
    $this->db->select('*');
    $this->db->from('contentImagesTable');
    $this->db->join('contentTable', 'contentTable.contentId = contentImagesTable.contentId');
    $this->db->join('categoryTable', 'categoryTable.categoryId = contentTable.categoryId');

    $query = $this->db->get();
    return $query->result_array();
}

The array that is returned is looks like this, I have cut the size down for readability.

    Array

            [contentBody] => <p>The Midlands based Group, with turnover in excess of &pound;21M, appointed Bang in 2008 following an open pitch of over 40 agencies. Bang's work began with an extensive marketing research strategy that challenged the Group's former positioning and brand structure.</p>

<p>The research unveiled that the housing sector demanded a values-led Group. This led Bang to develop the brave &lsquo;Together for the Right Reasons' positioning for Housing Plus.</p>
<p>Chris Garratt, Marketing Director at Bang explained "The housing sector has witnessed wholesale change in recent years. Much to tenant's dismay, many associations and Groups appear to be losing touch with their roots, we wanted to develop a Group for associations who place principles at the heart of their corporate strategy".</p>
<p>The repositioned sub-brands also play an important role in the Group's revised brand by highlighting Housing Plus' willingness to embrace and nurture individual identities. Chris Garratt continued "By adopting a &lsquo;house of brands' hierarchy from the outset, Housing Plus has sent out a strong message to prospective strategic partners".</p>
<p>Bang handled all aspects of work for the redevelopment of the three brands, including research, brand creation, naming, positioning, internal branding and communications, advertising, the brand launches, building the brands' on-line presence and the creation of a powerful brand film &ndash; which is already attracting significant interest from across the sector.</p>

I need a way that I can get all the content images associated with the same content title in one group and then display under the content title.

Can anyone help?

Answer 1

But long winded but you could do something like...

$titles = array();
foreach ($query->result_array() as $row) {
    $title = $row['categoryTitle'];
    if (!in_array($title, $titles)) {
        $titles[]['title'] = $title;
    }
}

for ($i = 0; $i < count($titles); $i++) {
    $title = $titles[$i]['title'];
    $this->db->select('*');
    $this->db->from('contentImagesTable');
    $this->db->join('contentTable', 'contentTable.contentId = contentImagesTable.contentId');
    $this->db->join('categoryTable', 'categoryTable.categoryId = contentTable.categoryId');
    $this->db->where('categoryTitle', $title);
    $query = $this->db->get();
    foreach ($query->result_array() as $row) {
        $titles[$i]['images'][] = $row['contentImagePath'];
    }
}

This question is kind of similar, isn't it: http://stackoverflow.com/questions/2495473/can-i-do-this-with-just-sql

I'm having to do this sort of thing as well in my project and my plan was to join the tables and then manually build the array from the returned rows. I would then pass that array back to the controller and then to the view.

I'm not sure this is the best way to go about it, but everything I've read indicates that it is.

This was another post I ran into when I was researching - http://stackoverflow.com/questions/1186227/sql-selecting-parents-and-their-children
