Random number in html/php link


Question

I'd like to generate a random number from between 1 and 5000,

This is how a link normally looks on my website - http://mysite.net/in...ils.php?mid=754

The code for this is generated by <a href="http://mysite.net/index.php/details.php?mid='.$v['id'].'"> (the number is chosen depending on which link is selected. - the ID is being retrieved from a database)

I'd like to create a seperate link that whenever its clicked it throws a random number in place. Can anyone help me achieve this?

<a href="http://mysite.net/index.php/details.php?mid=<?php echo rand(1,15000); ?>">LINK</a>
[/CODE]

That should do it

If it is already between PHP tags then

[CODE]
<a href="http://mysite.net/index.php/details.php?mid='. rand(1,15000) .'">LINK</a>
[/CODE]

Thanks that worked :D

I do however have a slight problem, in a few cases there is an ID missing (when I've made a mistake and deleted an entry in the database) so it throws up an error when its tries to retrieve 54 for example and there isn't a 54 in the database.

Is there any way around this?

Only way i can see is either do an if on the details.php page to say "if the returned query row count is 0" then display a friendly error or write function that will grab all the ID's from a database and then randomize a number from that.

Is this a site you've made yourself or is it running on an existing software?

Forget the random ID in the URL. Just create a page that randomly selects a page from your database. Use SQL to do this.

Depending on what database you're using, it will look something like this:

SELECT * FROM table
ORDER BY RAND()
LIMIT 1[/CODE]

This is how you'd want to implement something like StumbleUpon.

Do I just stick that code in a php file?

No, you would have to modify the code that reads the page-id from the URL and uses it to look up the page in the database. Somewhere, there will be code that looks like:

SELECT * FROM table WHERE pageid=mid[/CODE]

[color=#282828]That code will return the data for the page that was specified in the URL. Instead, you want something more like:

[CODE]SELECT * FROM table ORDER BY RAND() LIMIT 1[/CODE]

[/color]

[color=#282828]Of course, you have to change the part that says "table" to the name of the table you are reading in the database.[/color]

    • Amazon lays off more staff across Goodreads and Kindle divisions by Hamid Ganji Dozens of Amazon employees working on the retailer's book divisions have been laid off. As reported by Reuters, Amazon confirmed that it's cutting jobs across the Goodreads review site and Kindle units, which impacts fewer than 100 workers. Amazon says the recent layoffs across Goodreads and Kindle divisions are meant to improve efficiency and streamline operations. The giant retailer has constantly reduced staff across various divisions over the past few years. According to CEO Andy Jassy, reducing headcounts helps the company to eliminate bureaucracy. "As part of our ongoing work to make our teams and programs operate more efficiently and to better align with our business roadmap, we've made the difficult decision to eliminate a small number of roles within the Books organization," an Amazon spokesperson said. Layoffs recently impacted employees in Amazon's Wondery podcast division, devices and services units, communications, and in-store staff. However, Amazon's Q1 results show the retailer has added about 4,000 jobs compared to Q4 2024. After the Covid pandemic settled down, many companies began laying off thousands of staff they hired during the pandemic to respond to growing demands. The layoff trend among tech firms still exists today, and AI has amplified it. The latest data shows that in 2025, about 62,832 tech employees were laid off across 141 tech companies. Also, 152,922 tech employees across 551 companies were laid off in 2024. More layoffs are expected to occur due to declining economic growth, tariffs, and the expansion of AI across companies. Amazon is also gearing up to double down in AI investments and robotics. The company has recently announced the forming of a new agentic AI team to develop an agentic AI framework for use in robotics. Also, a new report by The Information indicates that Amazon has begun testing humanoid robots for package delivery.

    • OpenAI responds to The New York Times' ChatGPT data demands by Pradeep Viswanathan The New York Times has sued OpenAI for the unauthorized use of its news articles to train large language models. As part of the ongoing lawsuit, the NYT recently asked the court to require OpenAI to retain all ChatGPT user content indefinitely. The NYT's argument is that they may find something in the data that supports their case. Brad Lightcap, COO of OpenAI, wrote the following regarding the NYT's sweeping demand: OpenAI has already filed a motion asking the Magistrate Judge to reconsider the preservation order, since indefinite retention of user data breaches industry norms and its own policies. Additionally, OpenAI has also appealed this order with the District Court Judge. Until OpenAI wins its appeal, it will be complying with the court order. The content defined by the court order will be stored separately in a secure system and will be accessed or used only for meeting legal obligations. Only a small, audited OpenAI legal and security team will be able to access this data as necessary to comply with our legal obligations. As of early 2025, ChatGPT has over 400 million weekly active users, and this data retention order will affect a significant number of them. OpenAI confirmed that ChatGPT Free, Plus, Pro, and Teams subscription users, and developers who use the OpenAI API (without a Zero Data Retention agreement) will be affected by this order. ChatGPT Enterprise, ChatGPT Edu, and API customers who are using Zero Data Retention endpoints will not be affected by this court change.
