Magento 1.9.2.4 – Fix Non-Numeric Value Encountered Error

magento-1magento-1.9magento1.9.2.4

guys,

I recently installed an extension to display the installment price.

However, the following error appears in the log:

Warning: A non-numeric value encountered in /app/code/community/Contardi/Installments/Helper/Data.php on line 87

The code in the Data.php file is as follows:

public function getDescontoPrimeiraParcela($valorParcela)
{
    $percentual = $this->descontoPrimeiraParcela;
    $desconto = (float)(str_ireplace(',', '.', $percentual) / 100); // line 87
    if ($desconto) $valorParcela -= ($valorParcela * $desconto);
    return $valorParcela;
}

Does anyone know what can it be?

Thanks.

Which value do you get back for $percentual = $this->descontoPrimeiraParcela? It seems like it's not returning a numeric value. Maybe there's a percent sign in it or something that cannot be casted to a proper float value.

In general you could disable PHP Warnings through editing the index.php, more information about it here: https://www.php.net/manual/de/function.error-reporting.php

Magento – Magento 1.9.2.3 isn’t finding Data helper in custom extension

After hours of fiddling and searching, I found the magic sauce in a comment thread on this SO post. I had to expand the comments to find it!

For posterity and in case you're banging your head on the same thing, here's the solution.

Check your logs (tail -f <magento_root>/var/log/system.log).

If you have copied any XML from the web, view it in a text editor and ensure that you do not have invisible characters!

Does not work:

<config>
    <menu>
        <namespace module="namespace_package">
            <title>Namespace</title>
            <sort_order>200</sort_order>
                <children>
                    <overview>
                    <title>Overview</title>
                    <sort_order>1</sort_order>
                    <action>adminhtml/namespace/index</action>
                </overview>
            </children>
        </namespace>
    </menu>
    <acl>
     <resources>
        <admin>
            <children>
                <namespace module="namespace_package">
                    <title>Top Level Namespace Menu Item</title>
                    <sort_order>1</sort_order>
                </namespace>
                </children>
            </admin>
        </resources>
    </acl>
</config>

Solution: make sure your module defined for the <config><menu> in adminhtml.xml is correctly using ONLY the namespace and not Namespace_Package or namespace_package.

This works:

<config>
    <menu>
        <namespace module="namespace">
            <title>Namespace</title>
            <sort_order>200</sort_order>
                <children>
                    <overview>
                    <title>Overview</title>
                    <sort_order>1</sort_order>
                    <action>adminhtml/namespace/index</action>
                </overview>
            </children>
        </namespace>
    </menu>
    <acl>
     <resources>
        <admin>
            <children>
                <namespace module="namespace">
                    <title>Top Level Namespace Menu Item</title>
                    <sort_order>1</sort_order>
                </namespace>
                </children>
            </admin>
        </resources>
    </acl>
</config>

Magento 1.9 – PHP 7.2 Patch: Customer Registration Error ‘A Non-Numeric Value Encountered’

https://github.com/Inchoo/Inchoo_PHP7/issues/125

[...] But I see that PhpMath class isn't used by Zend when bcmath extension is enabled, so enabling bcmath in php could maybe solve the problem?

That did the job for me.
