    According to stats, more than 13% of the websites using the Magento platform are using it for eCommerce features. This massive popularity of Magento has made it the second most-used platform for online retailing and eCommerce solutions. Frankly, the platform is preferred by users and Magento developers alike for its high-end customization options and advanced features.

    It wouldn’t be wrong to say that Magento delivers intense functionality with promising customization features. For this reason, Magento has become an apt choice for eCommerce businesses in need of customer services, store management, feedback, rewards, and sales. Now, the eCommerce market is extremely saturated, which means there is little (if any) place for any mistake when it comes to Magento development and customization for eCommerce stores.

    To ensure an interactive, and engaging online store, apt to attract users, the developers need to prioritize the customer, client, and visitor requirements while adapting to the cutting-edge needs of websites for increasing the sales chart. To help you out, we are sharing five common mistakes that Magento developers make while developing the Magento store!

    SQL Query Inside The Loop

    This is the first yet the biggest mistake made by Magento development services and developers. To illustrate, the developers often load the SQL queries inside the loop to reduce the product properties. However, the query inside is the sign that it has been operated once and will tarnish the performance standards.

    In addition, SQL query inside the loop is a mistake for Magento store developer because the count of process repetition actually depends on the count of objects. For instance, if you have lesser data in the loop, the website performance will be quicker and efficient. However, low data quantity will slow down the performance of the website.

    That being said, developers can alternatively use JOINs, subselects, GroupBy, and Batch inserts. This is because these solutions will improve the store performance even with more data.

    Loading The Models Various Times

    Before we begin with the details, we are talking about loading the same models at various times. For instance, if you load the same model twice, it will lead to bigger blunders. To illustrate, if a model named “resolution” is available in the code and you add another model with “resolution” in it, it will result in overstepping.

    This is because when the end-users run the model, how will they differentiate the two models. Now, let us help you out by sharing the information. In case the same model is imported or loaded twice, one model will have a one-time evaluation. To summarize, if the same model is imported multiple times, the same model instance will be received.

    Inefficient Utilization Of Memory

    For the most part, the average servers tend to have 16GB of memory, but still, inefficient utilization of memory can result in errors. Generally, the Magento developers opt for the database adapter method for fetching the widespread results. However, it can lead to intense and extensive demand for network resources and systems.

    When it comes down to the huge datasets, they require widescale network resources and systems for processing purposes. As a result, it will restrict and limit the results. However, it can be fixed if you apply the correct limits and use appropriate filters. Lastly, the Magento developers must avoid processing data more than necessary and eliminate fetching.

    Redundant Utilization Of Datasets

    This mistake is usually made by inexperienced and beginner Magento developers. So, they tend to recover the complete data sets even if they only need limited numbers and data. This is because the data collections should be utilized to a specific limit. Magento developers often misuse the collections and forget to apply the limitations on the query results of the collection.

    Consequently, it leads to redundant utilization of the datasets. That being said, Magento developers should consider putting limits on the datasets, and it will improve the Magento store performance. Even more, it will enhance the scalability.

    PHP Code Optimization

    If the Magento developers are new and beginners in the field, they often forget to use the right PHP code optimization techniques. For instance, they forget the implementation of inefficient use of the count feature. The inefficient use of the count feature is generally better for daily tasks and can fluctuate with the utilization of loops.

    Magento developers need to keep in mind that PHP codes are not suitable for performing the loop invariant code motion on an automated basis. That being said, it’s best to move the count call to the exterior side of the loop. In addition, there are other PHP mistakes that Magento developers make, such as;

    • Implementing queries in the loop
    • Leaving the arraying reference after the loop (the for each loop)
    • Inefficiency and head fakes when it comes down to memory utilization
    • Misinterpreting the behavior of “issst”
    • Ignoring the standards of coding
    • Confusing the reference and value returns
    • Not valuing the Unicode UTH-8 errors
    • Considering that PHP supports the character data

    Modifying The Core Files 

    For the most part, the developers have shorter deadlines to customize and build the Magento stores. For this reason, Magento customization company often try to modify the core files as a quick fix to optimize the customization needs of the customers. This is considered patchwork development and can lead to errors and adverse impacts on eCommerce websites on a long-term basis.

    That being said, Magento developers need to protect the core files for upgrades and improvements in the future. Magento developers should create the module and override the block, model, and controller through rewriting techniques. In addition, Magento developers can modify the core files by creating a copy of the folder structure. The folder structure should be copied to the local folder.

    Additional Things To Consider

    When it comes down to the Magento store development, it is better to use the Magento designer guides because it helps style the websites. Magento has an exceptional fallback system, which means the developers can easily customize the store without tweaking the default theme. The development mistakes usually belong to the collection, models, Magento loop, and PHP codes.

    For this reason, it’s best to use accurate codes and remain attentive while applying the codes. In addition, the developers should restrict the computation. On top of everything, Magento developers must learn the framework features and learn how to use the features correctly. Lastly, developers must update the PHP version regularly. Truth be told, these steps will make the Magento development cost affordable and won’t result in inefficient outcomes.
