    Default [Done v1.5.6] PHP Warning: A non-numeric value encountered... - PHP 7 warnings

    I have had a couple of these debug warnings with PHP 7.1. No doubt there will be more...

    1) in advanced_search_result_header.php

    I changed

    $rate = $currencies->get_value($_SESSION['currency']);
    if ($rate) {
    $pfrom = $_GET['pfrom'] / $rate;
    $pto = $_GET['pto'] / $rate;}
    to
    $rate = $currencies->get_value($_SESSION['currency']);
    if ($rate) {
    $pfrom = (float)$_GET['pfrom'] / $rate;//steve added float for PHP 7 warning
    $pto = (float)$_GET['pto'] / $rate;//steve added float for PHP 7 warning
    }
    Note this was provoked by an url like this
    SHOP_ROOT/index.php?main_page=advanced_search_result&keyword=asas&search_in_description=1& categories_id=&inc_subcat=1&manufacturers_id=&pfrom=&pto=&dfrom=&dto=

    2) functions_taxes.php

    I changed
    // Calculates Tax rounding the result function
    zen_calculate_tax($price, $tax = 0) {
    $price = $price;
    $tax = $tax;
    //eof global $currencies;
    return $price * $tax / 100;
    }
    to
    // Calculates Tax rounding the result
    function zen_calculate_tax($price, $tax = 0) {
    $price = (float)$price; //steve added float for PHP 7 warning
    $tax = (float)$tax; //steve added float for PHP 7 warning
    //eof global $currencies;
    return $price * $tax / 100;
    }

    Default PHP Warning: A non-numeric value encountered... categories_ul_generator.php

    V1.5.5e
    PHP v7.1.1
    Stirling Grand Template
    css_js_loader
    Dynamic Price Updater
    One page checkout
    SBA
    User tracking
    Zen Magnific
    CEON
    Elastislide & Responsive Image Gallery
    Dynamic Attr. Filter

    This might be the place for these errors so,

    I have a similar debug error

    PHP Warning: A non-numeric value encountered in C:\mylocalserver\www\mydomain.co.uk\includes\classes\categories_ul_generator.php on line 58

    said line is:
    PHP Code:
     $result sprintf($this->parent_group_start_string, ($submenu==true) ? ' class="level'. ($level+1) . '"' '' ); 
    error remedied, with no obvious effect, by changing to:

    PHP Code:
    $result sprintf($this->parent_group_start_string, ($submenu==true) ? ' class="level'. ($level) . '"' '' ); 
    it would be good to know the actual effect that had. The line comes from this block:
    PHP Code:
    function buildBranch($parent_id$level 0$submenu=true$parent_link='')
        {
            
    $result sprintf($this->parent_group_start_string, ($submenu==true) ? ' class="level'. ($level+1) . '"' '' );
            
            if ((
    $this->data[$parent_id])) {
                foreach(
    $this->data[$parent_id] as $category_id => $category) {
                    
    $category_link $parent_link $category_id;
                    if ((
    $this->data[$category_id])) {
                        
    $result .= sprintf($this->child_start_string, ($submenu==true) ? ' class="submenu"' '');
                    } else {
                        
    $result .= sprintf($this->child_start_string'');
                    }
                    
    $result .= str_repeat($this->spacer_string$this->spacer_multiplier 1) . '<a href="' zen_href_link(FILENAME_DEFAULT'cPath=' $category_link) . '">';
                    
    $result .= $category['name'];
                    
    $result .= '</a>';
                      
                    if ((
    $this->data[$category_id]) && (($this->max_level == '0') || ($this->max_level $level+1))) {
                        
    $result .= $this->buildBranch($category_id$level+1$submenu$category_link '_');
                    }
                    
    $result .= $this->child_end_string;
                }
            }
            
            
    $result .= $this->parent_group_end_string;
            return 
    $result;
        } 
    I have the original line 58 in
    ZC v1.5.4/PHP v5.6.5
    ZC v1.5.5a/PHP v5.6.5
    both of which worked fine, I suspect it might be a PHP 7 issue.

    What do you think?

    don't like it. changes what the function is doing. i would change the line to:

    PHP Code:
    $result sprintf($this->parent_group_start_string, ($submenu==true) ? ' class="level'. ((float)$level+1) . '"' '' ); 
    note that this is a warning, and php 7 now issues warnings when attempting arithmetic operations on strings or null values. while it is a change i would hardly call it an issue with php7.

    That's great, thank you for clarifying that.

    Edit: fixed that, more of the same at:

    ..\includes\functions\functions_taxes.php on line 172.

    torvista was right.

    The CORRECT way to fix this one is shown here: #18 ... everything else is a bandage.

    Had a similar error on a client's site (ZC 1.5.5e) asf:

    [19-Oct-2017 16:33:21 UTC] PHP Warning: A non-numeric value encountered in includes/modules/pages/advanced_search_result/header_php.php on line 368
    The recommended fix

    https://github.com/zencart/zencart/pull/1437/files

    made no difference at all.

    So, I applied torvista's suggestion which appears to work. Not saying it is the *correct* fix but the cart now runs without errors.

    the recommended fix deals with tax problems, not with advanced_search_results....

    your error log clearly states an issues with advanced search results, which is a different fix than the tax one. so i would recommend applying them both.

    i find @torvista s work solid and agree with most things he brings up; certainly in this case, it does address your issue....
