    text
    copied!<p>I have an array having 2-3 titles. eg. 'Get 20% Off' , 'Receive 40% Savings' , 'Grab 10% discounts' etc. I would like to get the numeric value before '%' sign. and pass this numeric value into a html form as inputs. and in return the form would calculate a percentage amount. and display all the results.</p> <p>Right now i have managed to make this work for a single title. but i am not able to get a array of titles.</p> <p>my code is as follows -</p> <p>//code for getting all the titles //putting it into an array called '$array'</p> <pre><code>foreach($array as $str) { if(preg_match('/(\d+)\%/i' ,$str,$m)) { echo $m[1],"\n"; ?&gt; &lt;?php } } ?&gt; </code></pre> <p>//the above code extracts the amount before the percentage off sign. and the below code passes it as a input to the form (name=a). and other input (name=b) is coming from a different source. thats working fine. for calculation consider that input to be 100. I would need to calculate the percent value w.r.t 100. for eg- if input a is 5, then another input b is 100. the value to be outputted would be 5.</p> <pre><code>&lt;form name="form1"&gt; &lt;input type="text" name="a" value="&lt;?php echo $m[1]; ?&gt;" size=5&gt; &lt;input class="budget-sidebar" type="text" name="b" id="amount" size=5&gt; </code></pre> <p>the below html is used for displaying the calculated value and submitting the form.</p> <pre><code>&lt;input type="text" name="total1" value="ans1" size=5 maxlength=4&gt; &lt;input type="button" value="Calculate" onClick="calc1(this.form)"&gt; &lt;/form&gt; </code></pre> <p>the below javascript function is responsible to take the inputs and calculate the value and displaying it.</p> <pre><code>&lt;SCRIPT LANGUAGE="JavaScript"&gt; &lt;!-- Begin function calc1(form) { a = form.a.value/100; b = a*form.b.value; form.total1.value = b; } // End --&gt; &lt;/script&gt; </code></pre> <p>i have posted a similar question requesting for different suggestions &amp; this is supposed to be a different query. thanks.</p>
