PHP loop not working

I have a modal that is inside of a loop.
And i am trying to make a new loop inside of the loop.

I am trying to loop this
Lets call this Color loop

$get_color = "SELECT * FROM gallery2 WHERE number_='$number'"; // i want to get the data from $number that comes from the button from another function.
$run_color = mysqli_query($conn,$get_color);
while ($rows = mysqli_fetch_assoc($run_color)){
	$id=$rows['id']	;
	$color=$rows['image'] == '' ? '' : ' <div class="col-sm-3 col-md-3">

	<div class="thumbnail" >
		<h4 class="text-center"><span class="label label-info center-block" style="background-color:#CF000F;">Liso '.$number.'</span></h4>
		<a id="carousel-selector-0" ><img src="../'.$rows['image'].'" ></a>
                    <div class="caption">
                    <div class="row">
		<button type="button" class="btn btn-primary actions add btn-block " data-action="add"   product_id="'.$id.'"  ><i class="fa fa-cart-plus" aria-hidden="true"></i></span> Add</button>
		     </div>
		     </div>
                </div>
	       </div>';


			}

Open in new window


The problem is that my modal is already in a loop
Modal loop

$sql = "SELECT * FROM gallery2 WHERE liso = 1 ";
			$run = mysqli_query($conn,$sql);
			while ($rows = mysqli_fetch_assoc($run)){
			 $vari = $rows['variante'];
			 $num = $rows['title'];
			 $isLiso = $rows['liso'];

			 $id=$rows['id'];
			 if($vari< 1){
			        $dash="";
			         $vari="";
			        }else{
			          $dash="-";
			         $vari = $rows['variante'];
			        }
                               $dashcol="-";
				
				$variI = $rows['variante'];
				$number=$num.$dashcol.$variI;
				
				echo '<div class="modal fade" id="lisos'.$number.'" role="dialog">

<div class="modal-dialog modal-xl">
<div class="modal-content">
<div class="modal-header">

<div class="btn-group pull-right">
<button type="button" class="btn btn-default pull-right" data-dismiss="modal" aria-hidden="true">×</button>
</div>
<h3 class="modal-title">'.$num.''.$dash.''.$vari.'</h3>
</div>
<div class="modal-body">
		
            <div class="col-md-12"> 

			 '.$color.' //////////Need to loop here the Color loop

            </div>
			
     
 <div class="clearfix"></div>
</div>
</div><!-- /.modal-content -->
						
</div><!-- /.modal-dialog--->
    	
</div><!-- /.modal ending  -->

';} 

Open in new window


Another problem is that both loops are in one function called function Modal_Color().

So its like this ...
function Modal_Color{
///Color loop

///Modal loop

}

And what fires the modal is a buttons from another function.
What i am trying to do is display multiple products in the modal that contains the data from the Color Loop.
You will see that $number is not defined in the query in Color loop.
Only inside of the modal loop.
So all this is not working.

How can i loop the Color loop inside of the modal loop?

This is how to nest the colour loop inside the modal loop

$sql = "SELECT * FROM gallery2 WHERE liso = 1 ";
$run = mysqli_query($conn, $sql);

while ($rows = mysqli_fetch_assoc($run))
{
    $vari = $rows['variante'];
    $num = $rows['title'];
    $isLiso = $rows['liso'];

    $id = $rows['id'];
     
    if($vari < 1)
    {
        $dash = "";
        $vari = "";
    }
    else
    {
        $dash="-";
        $vari = $rows['variante'];
    }

    $dashcol = "-";
    $variI = $rows['variante'];
    $number = $num.$dashcol.$variI;

    echo '<div class="modal fade" id="lisos'.$number.'" role="dialog">

<div class="modal-dialog modal-xl">
<div class="modal-content">
<div class="modal-header">

<div class="btn-group pull-right">
<button type="button" class="btn btn-default pull-right" data-dismiss="modal" aria-hidden="true">×</button>
</div>
<h3 class="modal-title">'.$num.''.$dash.''.$vari.'</h3>
</div>
<div class="modal-body">

            <div class="col-md-12">';
    
    $get_color = "SELECT * FROM gallery2 WHERE number_= $number ";
    $run_color = mysqli_query($conn, $get_color);
    
    while ($crows = mysqli_fetch_assoc($run_color))
    {
        $id = $crows['id']	;
        $color = $crows['image'] == '' ? '' : ' <div class="col-sm-3 col-md-3">

	<div class="thumbnail" >
		<h4 class="text-center"><span class="label label-info center-block" style="background-color:#CF000F;">Liso '.$number.'</span></h4>
		<a id="carousel-selector-0" ><img src="../'.$crows['image'].'" ></a>
                    <div class="caption">
                    <div class="row">
		<button type="button" class="btn btn-primary actions add btn-block " data-action="add"   product_id="'.$id.'"  ><i class="fa fa-cart-plus" aria-hidden="true"></i></span> Add</button>
		     </div>
		     </div>
                </div>
	       </div>';

    }               

    echo $color.'</div>		   
 <div class="clearfix"></div>
</div>
</div><!-- /.modal-content -->
</div><!-- /.modal-dialog--->  
</div><!-- /.modal ending  -->';
}

Great no errors!
But inside of my modal i am still getting only  one product,i checked in my DB i have 2 products for test inside of the modal.
The modal loop for each product in my gallery.
And each product have a sub product inside of the modal.
E.g

My cushion 1 have 3 colors on it drawing,(black,pink and red) so the color modal will load the cushions that has the same title.
exempleIts working but its looping one only.
modal
For this modal its suppose to be 2 products inside of it.

Oops! You have to save the results in an array. Use square brackets.
    while ($crows = mysqli_fetch_assoc($run_color))
    {
        $id[] = $crows['id']	;
        $color[] = $crows['image'] == '' ? '' : ' <div class="col-sm-3 col-md-3">

	<div class="thumbnail" >
		<h4 class="text-center"><span class="label label-info center-block" style="background-color:#CF000F;">Liso '.$number.'</span></h4>
		<a id="carousel-selector-0" ><img src="../'.$crows['image'].'" ></a>
                    <div class="caption">
                    <div class="row">
		<button type="button" class="btn btn-primary actions add btn-block " data-action="add"   product_id="'.$id[].'"  ><i class="fa fa-cart-plus" aria-hidden="true"></i></span> Add</button>
		     </div>
		     </div>
                </div>
	       </div>';

    }

and you may need to use a foreach loop to display them as well.

Your first solution did resolve my errors.
But it was looping only one product.
What i did was change a bit.

   echo '<div class="modal fade" id="lisos'.$number.'" role="dialog">

<div class="modal-dialog modal-xl">
<div class="modal-content">
<div class="modal-header">

<div class="btn-group pull-right">
<button type="button" class="btn btn-default pull-right" data-dismiss="modal" aria-hidden="true">×</button>
</div>
<h3 class="modal-title">'.$num.''.$dash.''.$vari.'</h3>
</div>
<div class="modal-body">

            <div class="col-md-12">';
    
    $get_color = "SELECT * FROM gallery2 WHERE number_= '$number' ";
    $run_color = mysqli_query($conn, $get_color);
    
    while ($crows = mysqli_fetch_assoc($run_color))
    {
        $id = $crows['id']	;
  ////////// //changed here to echo directly->    echo $crows['image'] == '' ? '' : ' <div class="col-sm-3 col-md-3">

	<div class="thumbnail" >
		<h4 class="text-center"><span class="label label-info center-block" style="background-color:#CF000F;">Liso '.$number.'</span></h4>
		<a id="carousel-selector-0" ><img src="../'.$crows['image'].'" ></a>
                    <div class="caption">
                    <div class="row">
		<button type="button" class="btn btn-primary actions add btn-block " data-action="add"   product_id="'.$id.'"  ><i class="fa fa-cart-plus" aria-hidden="true"></i></span> Add</button>
		     </div>
		     </div>
                </div>
	       </div>';

         }        

   echo '</div>	//changed here to echo this rest of divs only.	   
 <div class="clearfix"></div>
</div>
</div><!-- /.modal-content -->
</div><!-- /.modal-dialog--->  
</div><!-- /.modal ending  -->';

}
